The most important goal in event-driven wireless sensor networks is to transmit the event information to users as soon as possible. One of the most important factors that would make it possible to reach this goal is the design of efficient detecting protocols. In this paper, we present an efficient event detecting protocol (EEDP) specified for event monitoring applications. In the event occuring area,...
The most important goal in event-driven wireless sensor networks(EWSNs) is to transmit the event information to users timely. One of the most important factors that would make it possible to reach this goal is the design of efficient detecting protocols. In this paper we present an efficient event detecting protocol(EEDP) designed for event monitoring applications based on geographical routing. In...
Power control technology in wireless sensor network (WSN) is of great significance to ensure the network coverage, reduce the power consumption of the nodes, and optimize network performance. In this paper, a new power control based on routing protocol (PCBRP) in the MAC layer is proposed. It operates with the help of routing protocol and calculates optimal transmission power according to the distance...
In wireless sensor networks (WSNs), some unavailable areas often formes because some sensor nodes become unavailable due to energy exhausted, congestion, or disaster. In this paper, we propose a new micro sensor multi-path routing protocol (MSMRP) to cross around the unavailable areas when building up the routes. And we design a neighbor node table exchanging mechanism that can avoid the multiple...
In most of existing routing protocols of wireless sensor networks (WSNs), a route is set up through broadcasting the route request (RREQ) messages throughout the entire network, which often brings broadcast storm. In this paper, we propose a new gradient-based micro sensor routing protocol (GMSRP) to alleviate the broadcast storm. With the GMSRP, during the network initialization, the sink node broadcasts...
