Abstract:

Due to the ignorance of the relation between different collisions, traditional medium access control protocols cant achieve their anticipated collision resolution results. This paper proposes a novel way to distribute MAC accesses in MANETs based on collision classification approach and modified backoff schemes. The idea is to avoid cross collisions through dynamically allocated elementary windows which prevent intersection of spaces in which the backoff counters are decremented. It develops a policy to select an appropriate backoff value as a function of retransmission attempts, observed number of collisions etc. to minimize repeated collisions, and thus improves throughput, delay jitter, as well as fairness. The performance improvement is demonstrated convincingly using a wide range of simulations.
