ABSTRACT

Abstract-The presence of new mobile computing devices rise the tendency to use ad hoc networks in which each device connects to its neighbor without the need to connect to a fixed infrastructure network. Broadcasting is sending data packet from a source node to the rest of nodes in the networks; it is characterized by no acknowledgement packets and no request or clear to send dialogue packets. Broadcasting suffer from redundant rebroadcast, contention and collision, these drawbacks lead to increase the delay and the number of dropped packets caused by contention (i.e. degrade in the quality of service). Anew distance based broadcasting algorithm is proposed to enhance broadcasting in wireless mobile ad hoc networks, this algorithm is analyzed and tested using GloMoSim network simulator, the simulated results are used to compare with another two distance based broadcast algorithms.
