RLABP: A Receiver-deciding Location-Aided Broadcast Protocol for Mobile Ad Hoc Networks

Broadcasting in mobile ad hoc networks (MANETs) provides route establishment and control functionality for many unicast and multicast protocols and as such is widely utilized as a building block for other network layer protocols. Based on the analysis of existing broadcasting algorithms, a new broadcast protocol, Receiver-deciding location aided broadcast protocol (RLABP) is put forward in this paper. In this protocol, a node, upon receipt of a broadcast message, follows the following procedure to eliminate the number of relay nodes: it first divides the transmission coverage area of previous relay node into grids, and then finds out the proper grids to carry out rebroadcast; and if the node is located in the relay grid then it prepares to transmit the message after a designated period of time. A detailed explanation of RLABP algorithm is presented. Three other well-selected broadcasting protocols, i.e., simply flooding, DSNEBA, AHBP, are also evaluated via simulation in comparison with RLABP. The simulation results have shown improved performance of RLABP in many aspects
