Extract of sample "Security for Wireless Ad Hoc Networks"

Security for Wireless Ad Hoc Networks Abstract Technology is one of the most significant hallmarks in existence in relation to the interactions between people. In this particular case, it is significantly pertinent to note that there exist various instruments that are related to technology which have been instrumental in ensuring that the individuals in the world are connected, and the togetherness between them is further strengthened. For the acquisition of a better and knowledgeable understanding of these factors related to the phenomenon, it may be noteworthy to examine some of them. The technological development, which is in focus, in this case is in relation to mobile telephony. This is a technology, which has been in existence since the early 1980s. The other thing, which is worth noting, is that this technology seems to be rather dynamic for the purpose of keeping up with the various developments and changes that are taking place in the world. These changes are at times necessitated by the need for convenience on the part of users. It is this convenience that has brought about the aspect of wireless technology in mobile telephony. As opposed to just wireless communication, there are other newer developments that are taking advantage of this aspect of wireless communication. The precise example in this case is ad hoc mobile networks. Since the inception of mobile telephony, there are several technologies which have come to pass. In this case, these solutions and the technologies have been developed with the intention of overcoming the limitations, which are realized when making use of fixed infrastructure in the case of connectivity. It is also of the essence to note that the existence of this fixed infrastructure limits the adaption of wireless technology, which is more modern and new age. Bluetooth technology is the type of technology, which has brought to light the fact that wireless technology can be taken to another new level. Thanks to this technology, ad hoc networks have been realized. These are rather small mobile networks, which can also be said to be short-lived and are in operation in the absence of fixed telecommunication infrastructure. The main advantage of such networks is that they offer a rather quick deployment of wireless connectivity when fixed elements are not available. As opposed to just being situated in a single location, the various nodes that are available in the network are free to move around and fix or organize themselves in ways, which may not be prescribed for the users. This is the thing which about a significant level of convenience on the part of the user. There are several protocols which are applied for the purpose of bringing about the connectivity that comes thanks to these networks. The most popular one in this case is the IEEE 802.11 protocol for WI-FI networks, which brings about networking even at a low level when there is no presence of an access point. However, there is a flaw, which is exhibited in the case of such a network. This disadvantage is that the nodes, which exist in this network, are only in a position to send and receive information with each other. However, it is impossible for these nodes to route the information to other elements that are out of the network. The other thing, which is worth noting in relation to these networks, is that they can operate singly. In this case, they are standalone. At the same time, they can be connected to a larger network such as the internet, for example. Initially, it was a dream when it came to achieving connectivity anywhere, even on the go. However, with such networks this aspect has gone from dream to reality. The applications that run on mobile ad hoc networks are rather variant. These range from the large and dynamic mobile networks all the way to the small ones, which are also static and constrained by elements such as power supply. However, the algorithms, which bring about the proper functioning of such networks, are not dependent on the scale and size of the networks. However, these algorithms that brings about the functioning need to be properly distributed for the purpose of routing, bringing about proper network distribution not forgetting the scheduling of links therein. There are several factors, which have to be factored in when looking at the dynamics that are associated with the network. Examples of such include the quality of links on the network, the loss of propagation path not forgetting the topological changes, which may be experienced in the process. The network, which is established, ought to be one, which will be in a position to handle the various situations, which may come about in the course of operations. There are other notable things, which should be addressed properly depending on the type of network. An example in this case is with regards to the security of the network. There are various institutions, which will call for various security protocols depending on the nature of operations. For example, the nature of security in a military ad hoc network cannot be compared to the security level in a school network. For example, military networks are developed and designed in such a way that they cannot be intercepted. At the same time, the level of being detected ought to be as low as possible in order to deter any attempts by people who may be having the intention of breaching the security in the network. There are some types of mobile ad hoc networks, which can be identified. One of these is vehicular ad hoc networks. These are the types of networks, which allows for wireless communication between vehicles, say those that are in a convoy. Another application of this type of ad hoc network is in the communication between these vehicles and equipment, which may be located at the roadside. The other type of ad hoc network is the internet based ad hoc network. These are the ad hoc networks, which bring about the linkage between fixed internet gateway nodes and mobile nodes, which may be in the possession of ordinary people. In such a network, the normal complex ad hoc algorithms do not necessarily apply. There are certain concerns, which come about with regards to the attacks which may be perpetrated on ad hoc networks. These attacks come about on the various level of the network infrastructure. At the level of the application layer, the probable attack, which may come about, is through data repudiation and the inputting of malicious code in the system. At the physical layer, there may be the probability of eavesdropping, the jamming of traffic and the interference of the signals, which may be propagated. Communication is something, which is always evolving. At the same time, the infrastructure, which is applied in its fulfillment, is something, which has to be dynamic for the purpose of keeping up with these changes. It should be appreciated that there are various firms which are carrying out research and development for the purpose of bringing about further development on the technology and infrastructure which is currently in existence.
