PERFORMANCE COMPARISON OF QOS BASED ROUTING PROTOCOLS MBRR, REAR AND SPEED FOR WIRELESS SENSOR NETWORKS

Deepak Verma, Amardeep Kaur

Abstract: A wireless sensor network (WSN) is a collection of small randomly dispersed micro sensor nodes that have capability to sense, establish wireless communication between each other and do computations and process operations. A network especially wireless network strongly depends on the routing protocols to route the sensed data to the Base Station (BS) via some intermediate nodes. Due to fast emergence of the wireless sensing, a lot of work has been done on the various categories of routing protocols of WSN like location-based, data-centric, hierarchal routing protocols etc. to measure the network performance. But recent studies are provided with the evidence that Quality-of-Service (QoS) routing can enhance the network performance by increasing the network utilization, compared to routing that is not sensitive to QoS requirements of traffic. So in this paper, the focus is on evaluation and comparison of the network performance in the WSN having QoS routing. The comparison of the three QoS routing protocols MBRR (Majority Based Re-Routing), REAR (Reliable Energy Aware Routing) and SPEED (Stateless Protocol for End-to-End Delay) on the basis of various performance metrics such as Bit Error Rate (BER) vs. Signal-to-Noise Ratio (SNR), Average End-to-End Delay vs. BER, Packet Delivery Ratio vs. BER, Energy Consumed vs. BER, Network Lifetime vs. Energy Consumption, Throughput vs. BER and Throughput vs. SNR has been done in this research paper. On the basis of observed simulation results, it is concluded that the performance of MBRR is better than the performance of other two comparing protocols i.e. REAR and SPEED.
