Abstract


Wireless sensor network is a new information access platform with other network unparalleled advantage in access to information , real-time monitoring and gathering information network distribution area monitoring object , in order to achieve the complex within the specified range target detection great lack of make up wireless network information collection and tracking , with rapid deployment , invulnerability strong , has a broad application prospects . But more and more mobile node and optimize the overall performance of the network with the network introduced , the researchers gradually began sensor network supports node mobility into deeper research . This paper describes the concept of critical technical support nodes move in wireless sensor networks , characteristics , future trends and research directions ; from the default parameters on the basis of a detailed analysis of the LEACH protocol , the cluster head election algorithm and network topology optimized to reduce energy consumption , improve network throughput and extend network life 's purpose ; focuses on existing MAC protocol for wireless sensor networks and nodes have mobility after the impact of these agreements , and a support in the wireless sensor network node mobile high throughput dynamic polling MAC protocol - DPMAC ( dynamic polling MAC) ; mobility management of wireless sensor networks to achieve better results , based on RSSI and LQI quickly switch default parameters , subnet selection , sentencing guidelines and the switch fails to repair the improvements aim to overcome the existing problems in the traditional switching technology to reduce scanning latency handoff latency and packet loss rate , and improve network throughput amount and extend the network lifetime .
