Design and Development of Energy Efficient Protocol for WSN to Reduce Latency and Increase Scalability

Abstract

newlineWSN, a self organizing network with large number of sensor nodes spreading across a big geographic area is to accumulate environmental data and broadcast it directly to the base posting via intermediate nodes. WSN has recently attracted the attention of manufacturers of wireless device researchers, and consumers for its ability to remotely access and monitor data in various situations. WSNs have many advantages because of their low cost, small scale factor, and smart sensor nodes. WSN, an emerging technology in industries environmental monitoring, health care systems, and other areas has been impactful in recent years. newlineSensor nodes used in WSN are a collection of network devices. These nodes collect data and transmit it to the sink node, depending on the type of application. There is a chance that the network will become congested if many sensor nodes are transmitting data. Being a resource constrained device, a sensor node has some limitations in terms of memory bandwidth and energy due to which congestion is bound to happen resulting in a high number of packet drops delay scalability low throughput and significant energy waste due to retransmission. These disadvantages must be addressed and mitigated in a WSN. To overcome such limitations, an energy efficient routing for data transmission is needed to enhance the lifespan of the network. newlineA WSN which is a collection of unified sensor nodes works remotely to collect their surroundings. Routing a network is a difficult task. WSN routing has three form viz. proactive, reactive, and hybrid. Proactive routing protocols include DSDV and OLSR. Reactive routing protocols include AODV and DSR. ZRP and TORA are two examples of hybrid routing protocols based on required route formations between different nodes in the network. newlineEven though all nodes operate in different communications simultaneously the current analysis shows that more packet latencies occur and priority based transmission assignments are performed. newline newline
