An Efficient Qos-Balanced Routing Protocol in Wireless Sensor Networks

Objective: Packet transferring in the wireless sensor nodes becomes increasingly popular in the real world environment where the usage of wireless devices like mobiles phones is increased considerably. The main goal of this work is to introduce a novel approach for providing an efficient environment to transfer the packets across different number of nodes without packet loss by considering the factors of energy load level, congestion level, interference level and the communication capacity.

Method: This work introduces a novel approach called Efficient QoS-Balanced Routing Protocol (EQBR) approach which is used to transfer the packets from the sensor nodes to base station node by establishing the proper connection between them. The routing tree would be constructed in every round for transferring the packet by selecting the proper parent nodes. The parent node selection would be done by calculating the factors called the energy load level, communication capacity, interference level, and the congestion level. By calculating these factors, efficient selection of the parent node with better network life time without congestion could be selected.

Results: The performance evaluation was conducted in the network simulator (NS2) environment to prove the improvement of the proposed approach than the existing protocols performance. The comparison has been made by using the parameters called the Delivery ratio, Routing load, End to end delay and Remaining Energy. The comparison made were proves that the proposed methodology provides an better environment to transmit the packets across different number of nodes successfully.

Conclusion: The findings of this work demonstrate that the proposed methodology provides better result in terms of successful transmission of packets with improved energy consumption ratio.
