Wireless sensor networks are usually composed of autonomous nodes. Each networked node constructs its own neighbor table, routing table, and schedules internal tasks on its own. However, the inherently distributed control in a sensor network conflicts with the deterministic requirements when we develop real-time applications on top of wireless sensor networks. In this paper we argue for the cas...

Wireless sensor networks have been widely used in many applications such as military monitoring, target tracking and surveillance. Security issue is need to more concern. Routing protocol is the core technology of the network layer in wireless sensor networks. Many attackers disrupt the network with routing attack, which will do serious damage to wireless sensor networks. Consider the scare ene...

Wireless sensor networks (WSN) are generally distributed independent sensors which work mutually to monitor all or some physical or ecological conditions, such as temperature sound, pressure, moisture, humidity etc. They are sometimes called as Wireless Sensors and Actuators Networks (WSAN) as well. Wireless Sensor Networks work thoughtfully to pass their information through the network by capa...

Wireless sensor networks (WSN's) constitute a hefty zone of present-day research just because of advances to empowering advances in hardware and software. This research article scrutinizes the research issues/defies in (WSNs), which is an innovative computing standard that appeared or evolved from the blend of the Ad-hoc and "Supervisory Control and Data Acquisition " systems (SC...
