Performance evaluation of tree based data aggregation for real time indoor environment monitoring using wireless sensor network

A fundamental challenge in the implementation of Wireless Sensor Network is to reduce packet loss when channel bandwidth is limited and the energy of sensor is finite. In this paper, a suitable solution is provided for controlling packet loss through tree-based data aggregation and routing. From this perspective, a binary tree-based data aggregation and routing has been proposed which can reduce packet loss and energy dissipation which occurs due to unsuccessful packet delivery. Simulation result using NS-2 shows that binary tree-based data aggregation reduces packet loss up to 63.1% compared to cluster based protocol LEACH, up to 26.5% compared to chain based protocol PEGASIS. Moreover binary tree based data aggregation out performs both LEACH and PEGASIS with respect to the parameters end to end delay, packet delivery ratio and total energy consumption. Our proposed architecture integrates sensor network, mobile device, Access point and Cloud services as a single unit for real time monitoring. An experimental analysis of the proposed approach for indoor environment monitoring is carried out in the university laboratory to evaluate the performance in terms of time and energy consumption.
