To understand the complex behavior of a mobile ad hoc network, it is often necessary to proceed through the instantiation of a convenient theoretical model which can explain this behavior. The modeling tool we use in this paper is Erdös-Rényi approach. It emanate from random graph theory. Furthermore, since mobile wireless ad hoc and sensor networks are typically limited in memory resources and...
We propose a simple but effective algorithm to formulate growable communication graphs that exhibit (i) fast information dissemination, (ii) high scalability with negligible performance degradation, and (iii) very small diameter and short average path length. In particular, we use Borel Cayley Graphs (BCGs) as base network topologies. Previously, we reported that BCGs are one of the fastest information...
Collusion Attack is an attack against Mobile Ad Hoc Networks and is based on Optimised Link State Routing (OLSR) Protocol. In this attack, two attacking nodes collude to prevent routes to a target node from being established in the network. Packet Delivery Ratio (PDR) of nodes 2-hops away from the victim drops to 0%. Multi Point Relay (MPR) selection process in OLSR is exploited to achieve route denial...
Energy consumption in general and interference in particular are among the most critical issues in wireless networks. In this paper we present the E-BUM calculus, a Energy-aware calculus for Broadcast, Unicast and Multicast communications in wireless ad hoc networks. We formalize the notions of sender- and receiver-centered interference and provide efficient proof techniques for verifying the absence...
