无线传感器网络节点的能量有限,如何高效使用能量以延长网络寿命成为研究热点之一。针对HEED协议中簇首与基站直接通信能量消耗过大的问题,根据能耗模型与网络模型,提出一种基于HEED的簇首多跳融合路由算法,并用MATLAB在随机分布的传感器网络区域内进行算法的有效性仿真研究。仿真结果表明,新算法相对于HEED算法有效地延长了网络的生命周期。
The energy of wireless sensor network node is limited, and how to use energy efficiently to prolong network lifetime has become one of the hot topics. Aiming at the problem of energy consumption of direct communication between cluster head and base station in HEED protocol, a HEED-based cluster head multi-hop fusion routing algorithm is proposed according to energy consumption model and network model. MATLAB is performed in a randomly distributed sensor network area Simulation of the Validity of Algorithms. The simulation results show that the new algorithm effectively extends the life cycle of the network relative to the HEED algorithm.
