低开销负载均衡的改进型TORA协议
Improved TORA Protocol with Low Overhead and Load Balancing
摘要
Abstract
Aiming at the fast change of topology and easy chain congestion, large routing overhead, unbalanced load and short network life cycle in WSN, this paper proposes an improved TORA protoco(l TORA-p)with low overhead and load balancing, which automatically adjusts the maximum number of retransmission of OBM packet according to the network rate of change to reduce the number of unnecessary routing maintenance. Meanwhile, it uses link availability as routing metrics by combining MAC layer routing information to automatically balance the network load for achieving the goal of avoiding premature death and disconnection between critical path and nodes. Using the truetime2. 0 platform to set specific simulation environment, the performance of TORA-p is compared and analyzed. The results show that, TORA-p balances the network load, improves the network life cycle, and reduces routing overhead and delay, showing better data transmission capacity.关键词
