Analysis and simulation of MAC layer misbehavior in mobile ad-hoc networks

This work presents an analysis and simulation of the MAC layer misbehavior of the IEEE 802.11 standard, whose the principle is cheating at the protocol level to increase the transmission rate by greedy nodes to the detriment of other honest nodes. First the standard and its MAC layer are recalled. Secondly, a state of art on the research undertaken on misbehavior of the IEEE 802.11 Standard are presented. Then the results of simulation on a critical type of deterministic cheating (no Backoff) are given and analysed. We simulate the impact of the problem of greedy behavior on receiving, and analyze two crucial metrics of this misbehavior which can be adopted for the development of a detection/reaction strategy.
