摘要

传感节点能效是无线传感器网络(WSNs)的研究热点。而基于网格路由是提高能效的有效路由策略。为此

提出基于虚拟网格的格头连通路由(VGCR)协议。VGCR路由将网络划分为虚拟等尺寸的网格

每个网格产生一个格头

且每个格头具有休眠和活动两个状态。同时

由格头组建连通信宿的路由

且格头可在活动和休眠模式间自适应切换

使得并非所有格头同时参与路由

进而保存格头能量

延长了网络寿命。此外

为了处理信宿移动问题

VGCR路由仅对靠近于网格的一些格头更新路由。仿真结果表明:相比于同类算法

提出VGCR路由延长了网络寿命

提高了数据包传递率。

Abstract

Energy-efficient of nodes is the hot topic in wireless sensor networks（WSNs）. Grid-based routing is an efficient strategy for routing. Therefore

virtual grid-based grid head connected routing（VGCR） is proposed. The network is partitioned into virtual equal-sized grids by VGCR routing. Each grid generates a grid head. The routing path to the sink is established using grid heads. Grid heads are switched between active and sleep state. Therefore

not all grid heads take part in the routing process at the same time. This saves energy in grid heads and improves the network lifetime. To handle the movement of sink

VGCR routing only updates grid head which is near to the grid. Simulation results show that the proposed VGCR routing outperforms than similar algorithms in terms of network lifetime and packet delivery ratio.
