A Kind Of Blind Movement Control Algorithm Based On Signal Perception

Wireless Ad hoc network is a kind of complicated, acentric, self-organization, distributed, highly survivable and self-healing network system which consists of the wireless nodes. Ad hoc networks are formed by the self-organizing nodes without pre-erection of network infrastructure, only according to the specific circumstances or when we need to perform some emergency or temporary tasks. The mobility and failure of the nodes make changes at any time in network topology, so lots of difficulties are brought to the network's normal traffic. Therefore, maintaining and enhancing the network connectivity with the nodes'movement is not only an important research topic, but also a very important significance.The main contents of this thesis are as follows. Firstly, the related concepts of Wireless Ad hoc network were introduced. Secondly, I make a further introduction of movement control, and give deep summary and analysis of the classical algorithms for the movement control. Finally, I propose a blind movement control algorithm which is based on signal strength perception. When there is no information about the location and direction of the nodes, the blind movement control algorithm manages to control the nodes'movement and decrease the energy consumption for the network, which is depending on the strength information of the signal power and the designed mobile scheme about the network. The experimental results show that the algorithm not only increases the lifetime of the network based on optimizing the network energy consumption, but also indirectly optimizes the topology of the network and augments the connectivity of the network, in the end, the survivability of the Ad hoc network is generally enhanced.
