摘要:

广播是移动传感器网络的基本数据传输方式.针对现有广播算法中存在的冗余消息转发、信号冲突多等问题,提出一种基于位置的前向广播算法,分析了转发节点的位置对广播效率的影响,选择位置好的节点优先转发消息,减少了冗余消息转发.理论分析和仿真结果表明,与其他典型广播算法相比,前向广播算法不仅能保证广播的网络接收率,而且能限制转发的消息总数,降低网络能耗.

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
