For wireless sensor networks in wide-area cropland environments, the routing protocol would be optimal if it is scalable for wide network coverage, energy-efficient for long network lifetime, and adaptive with frequent topology changes. In this paper, a wireless sensor network system with EBGR (Energy-Balanced, Greedy forwarding Routing) protocol was developed based on Memsic IRIS nodes and TinyOS...
RPL is an IPv6 routing protocol arming at low power consumption lossy networks, which is very important to the development of wireless personal area network. By studying the discovery mechanism of RPL routing protocol in wireless sensor networks, we found that advantage routing nodes may die prematurely due to excessive use in current RPL mechanisms, which can cause the entire network life cycle greatly...
Besides the data reading function, the AMR network faced to next generation smart grid should has the functions of intelligent power transmission and line damage detection. The traditional AMR network can not meet the above requirement. We should work on new network architecture and optimize the protocol. We established the architacture of wireless sensor network, which is suitable for the next generation...
Aiming at the shortage of LEACH protocol, a new routing protocol CDS-EBRP is proposed in this paper, CDS-EBRP fully takes account of the energy consumption of individual node and entire network, a rational transmission path from nodes of network to sink node is searched, Aiming at the network topology changes which are caused by the dead of cluster head nodes, the invalidation of cluster member nodes...
Wireless sensor networks are envisioned by linking existing and emerging technologies of computers, wireless radio communications systems and sophisticated sensors to be used in application. Simulation is an important way to validate algorithm or protocol in wireless sensor networks. First we describe some typical simulation methods in WSN. Then we present a new simulation tool named Truetime and...
