基于跳数限制的高能效分簇路由算法
摘要
针对实时性较强的传感器网络
提出一种跳数受限的高能效分簇路由(HCECR)算法。HCECR算法采用存活时间(TTL)分簇的概念

新算法区分紧急和普通数据包
分别采取不同的转发机制
并在簇外多跳通信中引入边缘节点中继数据以降低簇外通信开销。仿真表明:新算法在保证数据包实时性的同时
提升了簇头与普通节点之间的负载均衡度
延长了网络生存周期。
Abstract
Propose a hop-constrained high energy-efficient clustering routing( HCECR) algorithm for strong realtime wireless sensor networks( WSNs). HCECR algorithm adopts the concept of time to live( TTL) clustering
and according to number of intra-cluster members and total minimum reachable energy consumption to build clustering construction considering both hop constrained and energy-efficiency. While the new algorithm distinguishes between urgent and general data packets
using different forwarding mechanism and introducing edge nodes relay data in outer-cluster multi-hop communication to reduce outer-cluster communication overhead. Simulations result shows that HCECR algorithm guarantees real-time characteristics of data packets
while improving load balance among cluster heads and normal nodes and prolong network lifetime.
