Wireless Sensor Networks (WSNs) is the vast area and developing very speedily now-a-days. This paper gives some of the major applications and critical limitations of WSNs like power and lifespan, communication bandwidth, memory size. Sensor nodes are working by node energy so the energy consumption is the essential issue in WSN. Routing in WSN consumes more energy than any other phase. Various routing...

In wireless sensor & actor network (WSAN), sensors are used to sense data from environment and send this data to the actor to take appropriate action. In semi automated architecture sensed data is forwarded to the actor and then to sink. This sensor network is used for road surveillance. There are many algorithms and protocols designed to reduce energy consumption. Because of different coordination...

Wireless sensor networks (WSN's) rely on various resource constrained nodes with limited energy, range, memory and computational power it is necessary to conserve battery energy so as to extend the life time of the given WSN deployment. In any WSN application measured data is gathered at regular intervals and the same is sent to the Base station (BS) by using neighbouring nodes. By forming clusters...
Wireless sensor networks(WSN) deploy a large number of sensor nodes in the monitoring region, collecting information which is sent to the target users by wireless means after simple treatment. As the wireless sensor nodes are usually deployed in inaccessible or high-risk areas and are in large numbers, replacing batteries becomes very difficult. The nodes are usually one-time battery-powered so there...
