Abstract:

Broadcasting is the basic manner to transmit data in mobile sensor networks. Aiming at the problem of redundant message relay and signal conflict and collision, a position-based forward broadcast algorithm (PFBA) is proposed. An analysis of the impact of the position forwarding node on the efficiency of broadcasting is made, the nodes in a favorable location have priority to relay message and the redundant messages are reduced significantly. Theoretical analysis and simulation results show that,compared with the other typical broadcast algorithms, PFBA can not only ensure the receipt ratio of the network in broadcasting, but limit the total number of forwarded messages, and reduce the energy consumption of the network.

Key words: mobile sensor network, relay area, broadcasting, node density
