Customized trans-regional and multi-hop routing method for wireless sensor network

Abstract

The invention discloses a customized trans-regional and multi-hop routing method for a wireless sensor network and belongs to the field of computer communication networks. According to the characteristics of a cluster routing algorithm and an alternate cycle in the wireless sensor network, a region concept is introduced, a control message is broadcasted to the entire network through a convergencenode, each node determines a region to which the node per se belongs according to the intensity of a received signal and direct communication among nodes which are far away from one another is avoided by limiting the regions. When cluster head election in a certain area fails in an alternate cycle process of the network, a supplementary cluster head is produced in the region and an appropriate multi-hop routing scheme is customized by constraining a trans-regional distance when inter-cluster routing is established. The method has the advantages of prolonging the survival time of the network, balancing node energy consumption of the network better, equalizing the distribution of dead nodes and expanding network scale which is suitable for a protocol.

Description

technical field [0001] The invention relates to a routing method LEACH-CS (LEACH-Customizable Zone-Spanned) for load balancing in a wireless sensor network, and belongs to the field of computer communication networks. Background technique [0002] In computer networks, routing protocols are responsible for forwarding data packets from source nodes across the network to destination nodes. The primary goal of traditional wireless network routing design is to provide high service quality and fair and efficient use of network bandwidth, and energy consumption is not the focus of routing considerations. However, in wireless sensor networks, the energy and communication capabilities of sensor nodes are limited, and the network requires routing protocols to utilize energy efficiently. At the same time, the number of nodes in sensor networks is often very large, and nodes can only obtain local topology information, which requires routing protocols to select appropriate paths based ...
