Grid Based Data Gathering in Multi-channel Wireless Sensor Network

Abstract

A data gathering protocol for multi-channel wireless sensor network is proposed in this paper. The sensor field is logically divided into some finite number of grids. Each grid is managed by a potential node called as grid manager. Each grid manager is also responsible for communicating aggregated data generated inside the respective grid to the base station either directly or via multi-hop communication. Proposed protocol can handle mobility of the sensor nodes. Numerical results are reported for performance evaluation of the proposed protocol. Future scope of the work is outlined.
