Topology topic has gained additional and special interest in the field of Wireless Sensor Networks (WSN). While WSN deployments are in general optimized by the known fundamental network topology, another trend is to enhance WSN by managing the network topology. Many propositions have been tested in this field, like topology directed routing, cooperating schemes, sensor coverage based topology control...
Group of small sensor nodes that are able of sensing, processing and transmitting data correlated to some occurrence in the network area are termed as Wireless Sensor Networks (WSNs). The sensor nodes have rigorous shortcomings, such as: bandwidth, short broadcasting range, limited CPU processing facility, memory and energy. Energy efficient routing algorithms have been mentioned in various articles...

The contribution of this article is two local recovery methods that may reduce overhead and make a more immediate reconnection of disconnected nodes compared to the soft state global recovery method applied in WSNs running RPL [1]. In addition, we perform an analysis of the implication to better judge the context where local recovery methods should be used. One of our suggested methods is based on...
Energy consumption represents a key element in the Wireless Sensor Networks (WSNs) design. Several factors can cause energy over consumption such as mobility, node position (relay or gateway), retransmissions... The network topology can also be a major cause of energy waste: a transmission in 1-hop requires a high energy, a transmission in K-hops requires a lower energy, even though, it can damage...
Wireless Sensor Network (WSN) is one of the emerging technological fields due to recent advancements and area of research.

The lifetime of a sensor node depends on its energy consumption. In order to achieve efficient use of the energy and extend the network's lifetime, this paper discusses the routing algorithm, focusing on the algorithm of SPIN. In the light of the problem of “blindly forward” and “data unaccessible” in SPIN, a new routing algorithm called SPIN-I is proposed, and we simulate it from two aspects with...
Energy management has become one of the main hurdles in the quest for autonomous and reliable Wireless Sensor Networks (WSN). This paper examines the emerging problem of increasing network availability by recharging, replacing or redeploying depleted sensors with the help of mobile entities. When mobility becomes a sensor's attribute and service stations are static, we propose passive vs. pro-active...
Wireless sensor networks are networks with nodes of low power and limited processing. Therefore, optimal consumption of energy for WSN protocols seems essential. In a number of WSN applications, sensor nodes sense data periodically from environment and transfer it to the sink. Because of limitation in energy and selection of best route, for the purpose of increasing network lifetime a node with most...
