摘要
提出了一种针对新型无线传感网络协义WirelessHART的低功耗分布式路由算法——DHEIRP(基于多跳的分布式能量迭代路由算法)。采用分布式的路由决策,加快了WirelessHART的网络组建和恢复速度。DHEIRP提出了一种新的能量迭代算法,选取最小跳数、接收信号强度、节点电池能量作为参数,能够最小化网络的传输消耗并平衡各节点的能量损耗。将DHEIRP同GBR以及HBRRP等已有算法进行了比较,证明DHEIRP在平衡节点能量和延长网络寿命方面有较大的优势。
An distributed low-power dissipation routing algorithm for the new wireless sensor network protocol Wire- lessHART called DHEIRP（distributed hop-based energy iteration routing protocol） is proposed in this paper. As a distributed routing protocol, DHEIRP can accelerate the network construction and recovery rate of WirelessHART. In DHEIRP, an energy iteration algorithm is proposed. Choosing the minimum hop count, RSS（received signal strength） and battery energy level as parameters, this protocol can minimize energy consumption of network transmission and balance energy loss among nodes. The numerical simulations have showed that DHEIRP excels GBR and HBRRP in terms of balancing load of the nodes and extending network lifetime.
