Position-based Wireless Sensor Network Routing Protocol for Strip Area

摘要

Przy wąskich pasku przestrzeni tradycyjne metody routing bezprzewodowej sieci czujników takie jak LEACH czy PEGASIS nie zdają egzaminu. W artykule zaproponowano nowy protokół PBCR - position based wireless network routing który łącz w sobie technikę klastrów i technikę łańcucha routingu.%Limited by the terrain, lots of Wireless sensor network (WSN) applications have to be deployed in a narrow strip area. Due to the narrow and strip network structure, traditional WSN routing algorithms such as LEACH and PEGASIS can not be applied in such applications directly, it's very necessary to develop a new routing protocol suit for the strip WSN. In order to improving communication efficiency of the strip network and saving the energy of the nodes, in this paper a Position-based Cluster routing (PBCR) protocol is proposed, which combines the clustering techniques with the chain routing techniques. The PBCR protocol divided the strip WSN into many belt-shaped region clusters and elected the cluster head through the position and dump energy of the nodes in the cluster, and forward data by cluster head chain. Simulation results show that the PBCR protocol can ensure a balanced use of node energy and prolong lifetime of the network, and has the obviously advantages in the narrow strip area than the LEACH and PEGASIS protocol.
