Wireless Sensor Networks - Scalability and Performance Issues: A Review
Noufal K. P · 2015
A Wireless sensor Network is an organized collection of a large number of small nodes with a capability of sensing, measuring and computing. These networks are mostly used for tracking, monitoring and controlling. The WSNs collect information from unattended locations and disseminate information to a specific user depending on the requirement. Data are routed amongst the nodes by using an appropriate routing technique. A number of factors affect the design of the routing protocols. Scalability one such important factor which influence the routing protocols. Scalability is that increase in the number of nodes after the WSN was established. Whether or not the WSN support the expansion is a very important factor in the design of the protocol. The routing protocols consider the sensor node characteristics in the design of the protocols. A routing protocol is said to be good when it is scalable and adaptive to the changes made in the topology. The protocols must work intact even though the size of network grows and the workload is increased.
