A Multi-path Routing Protocol Based On Valid Domain In Wireless Sensor Networks

With the rapid development of modern microelectronic technology, wireless communication technology, signal processing technology, and computer network technology, the development of traditional sensor information access technology has the direction from an independent model to a single integration, miniaturization, and to the intelligent, network-based. Wireless sensor networks (WSNs) become one of the most important and the most basic skills of information access. WSNs have been widely used in military, environment monitoring, medicine care and transportation control.Routing protocol is one of the important support technologies in WSNs, the performance of routing protocols is closely related to the performance of the network. With the development of WSNs, energy balance of network, the efficiency of transmission, and routing stability gradually become the focus considerations of routing protocol. Multipath routing in WSNs has gradually become one of the hot research topics. At the same time, there will be ineffective domains of empty of energy, congestion, and disaster in WSNs. In this dissertation, we firstly design a multi-path routing protocol based on effective domain in WSNs.We firstly study the current single path routing protocols of WSNs, AODV, MSRP, and multi-path routing protocols, analyze the factors and characteristics of current routing protocols considering. And then we propose a multi-path routing protocol based on valid domain,describe the routing scheme, message format and programming flow chart in details.At the same time,we propose a mechanism named "neighbor node table interaction mechanism"in braid nodes.Then we give a way to insulate invalid domain.Subsequently, we implement the protocol in micro sensor node MSR6680, which is a platform designed by ourself. Then, we analyse the performance by executing a series of comparisons with other similar protocols. The test results show that our mechanism performs better in stability, reducing the nonuniformity of energy consumption, and based on valid domain. We close this paper by summarizing our works and proposing future works.
