In this paper, we present the set of factors in the physical layer that are relevant to the performance evaluation of the routing protocols. Such factors consist of signal reception, path loss, fading and interference considerations. Therefore it would be desirable for routing algorithms in wireless ad hoc networks, to be able to select paths that are more likely to be stable. With this in mind we...
Vehicular Ad hoc Network (VANET) is a challenging network environment in which communication between vehicles in highly fading environments, like an urban scenario, is unpredictable and difficult. In order to analyze the performance of protocols and applications, network simulators like NS-2 use deterministic two ray ground radio propagation model. This model, however, poorly reflects the channel...
Huge interest and demand on information superhighway have pressed various telecommunications research fronts and lead to a new form of future Internet consisting of wired and wireless segments where resource-constrained devices such as palm pilots and sensors may become integral parts of the Internet rather than access-only platforms. One of the key design problems is the security in such heterogeneous...
