A straightforward approach to perform broadcast is by flooding. Unfortunately, flooding will cause some problems such as redundancy, contention, and collision. The Power-consuming features of flooding will lead to rapid battery exhaustion which will cause network unreliable. Hence, how to balancing remaining power of mobile hosts is a critical issue for a MANET. Our proposed power balance broadcast algorithms incorporate the residual battery energy of hosts into rebroadcast criterion. Each host rebroadcasts with a rebroadcasting probability, which is dynamically calculated by hosts’ residual power, number of neighbors, and average residual power of neighbors. Hence, low-power hosts broadcast with lower probability and high-power hosts broadcast with higher probability. We inhibit low-power hosts from frequently rebroadcasting to balance the remaining power of hosts and extend the lifetime of the network. According to the simulation results, power balance broadcast algorithms compared with the flooding approach can increase network lifetime by around 40%, reduce the standard deviation by 35%, and save a half of rebroadcasting. Our approach can balance the remaining power of hosts with high reachability, even in high mobility environments. Jang-Ping Sheu 許健平 2003 學位論文 ; thesis 28 zh-TW |
