A Time and Energy Efficient Data Gathering Method in Wsns

In the wireless sensor networks, resource constraints such as bandwidth and energy limitations, limited communication range, low storage and weak processing capacity motivate researchers to solving these problems. Presenting new algorithms such as efficient mobile agent based dada gathering methods would be a good solution for this case. Some of important advantages of mobile agent based data gathering methods are as follows: the ability of significant reduction in bandwidth usage by locally data gathering at each node, fault-tolerance and stable behavior in confronting with node or connection failure in networks, and having application oriented and user centric processing code. In this paper, we propose a data gathering method that uses multiple mobile agents and advantages of two proposed approaches for data dissemination task that can provide time and bandwidth efficiency and prolong network life time in wireless sensor networks. Our method provide better performance against well-known protocols in terms of various metrics such as execution time, energy and bandwidth usage, scalability.
