摘　　要：在无线网络中,由于传输过程会产生能耗,当部分节点能量耗尽时,网络的有效生命周期可能受到显著影响。鉴于此,文章研究了一种高效能量感知的路由分配算法,构建了一个无线网络传感器节点的能耗模型,该模型综合考虑了计算能耗、感知能耗、发射数据能耗和接收数据能耗4个关键方面。在进行无线网络路由分配时,充分权衡了有限的传输资源与延长网络有效生命周期的迫切需求。并基于上述能耗模型,设计了一种能效最大化的路由分配算法。测试结果表明,采用该算法的网络节点在运行至第400个周期时,平均剩余能量才降至零,这意味着设计的路由算法能够显著延长网络生存时间,并展现出卓越的传输性能。In wireless networks,due to energy consumption during transmission,the effective lifecycle of the network may be significantly affected when some nodes run out of energy.In view of this,the article studies an efficient energy aware routing allocation algorithm and constructs an energy consumption model for wireless network sensor nodes,which comprehensively considers four key aspects:computational energy consumption,perception energy consumption,transmission data energy consumption,and reception data energy consumption.When allocating wireless network routes,the urgent need to balance limited transmission resources with extending the effective lifecycle of the network is fully considered.And based on the above energy consumption model,a routing allocation algorithm that maximizes energy efficiency was designed.The test results show that the average remaining energy of network nodes using this algorithm only drops to zero after running for the 400th cycle,which means that the designed routing algorithm can significantly extend the network lifetime and demonstrate excellent transmission performance.
