Review on Wireless Sensor Network and its Secure Routing based on Middleware Sinks
The wireless sensor node can perform some basic computing tasks such as data measurement, filtering, aggregation, transmission/reception, and packet routing. These wireless network uses sink nodes to limit communication to short secures, decreasing power usage and optimizing the QoS. The sensor nodes are expected to autonomously perform under severe conditions for several periods, even years, without human intervention and maintenance. In particular cases, battery replacement or recharge may not also be possible. Thus, the premise of sensor networks to detect rarely occurring situations or to control chronically developing events mostly depends on the lifespan of the sensor network. The wireless sensor network is a promising technology in providing high bandwidth and network coverage. WSN helps the users to work online at anywhere and anytime by connecting with wireless mesh routers. WSNs distribute wireless services for a huge variety of applications. Even though all the nodes have many connections with the neighbor nodes, in the case that a specific node has a direct relationship with all the nodes. In some situations, the nodes have to communicate with the target node through many intermediate nodes. In such case, the latency of data transmission is high which in turn reduces the throughput of the network. Similarly, if there is a short route to reach the destination, then the same direction will be used by multiple nodes which also affect the throughput of the network. The above-identified connection increases the traffic in various associations and affects the performance of the system.
