Energy-Balanced Strategies for Hole Movement in Mobile Wireless Sensor Networks

چکیده
This paper considers a mobile WSN that contains a big hole. To achieve the full coverage purpose or enhance the tracking quality, three distributed algorithms are proposed for moving the existing big coverage hole to a predefined location. Firstly, the sink chooses a promising direction for hole movement. Then the Basic, Forwardonly and Any-Direction movement mechanisms are proposed to move the hole along the promising direction in a manner of minimizing the total power consumption or balancing the power consumption of the given WSN. Simulation results reveal that the proposed Holemovement mechanisms enhance the coverage of WSN and balance the power consumption of mobile sensor nodes. Keywords-mobile sensor, WSN, power-balance, holemovement, coverage.

متن کاملEnergy-Saving in Wireless Sensor Networks Based on Optimization Sink Movement Control
A sensor network is made up of a large number of sensors with limited energy. Sensors collect environmental data then send them to the sink. Energy efficiency and thereby increasing the lifetime of sensor networks is important. Direct transfer of the data from each node to the central station will increase energy consumption. Previous research has shown that the organization of nodes in cluster...
