Energy efficiency is one of the most critical research issues in the area of wireless sensor networks. This is due to severe resource limitations of sensor nodes, one of the approaches for prolonging the sensor network operable lifetime is to deploy an effective topology control protocol. This paper presents an algorithm called T-TMP algorithm which has been implemented on commercial hardware that...
This paper mainly discusses the problem of code distributed protocol, which is the code distributed protocol for TinyOS (Tiny Operating System) applied in wireless senser networks, Then redesign an new hierachical topological control structure with GAF and Deluge, which called GAFDeluge. The GAFDeluge turn off the node radio equivalent to cluster head in grid during distribution update code among...
Wireless sensor network (WSN) consists of tiny sensor nodes with sensing, computation and wireless communication capabilities. Now a days, it is finding wide applicability and increasing deployment, as it enables reliable monitoring and analysis of environment. The design of routing protocols for WSN is influenced by many challenging factors like fault tolerance, energy efficiency, scalability, latency,...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
