More recently, wireless sensor networks (WSN) have been widely recognized as a highly emerging technology. WSN is made up of a set of sensors, whose sole source of energy is the battery. As sensors are usually used in inaccessible areas, replacing or recharging the battery turns out to be almost impossible. It is actually, energy consumption which constitutes the major problem that causes too much...
Recently, wireless sensors networks (WSN) have become a subject of interest for many different applications. This type of network is composed of a large number of small nodes called sensors; are relatively limited in terms of energy, memory, computing power and throughput. These specific features require a specific routing protocol for WSN, among the routing solutions studied and proposed, the RPL...
A Wireless Sensor Network (WSN) is a particular ad hoc network which consists of a set of small size devices called sensors exploited in a defined geographical zone. The communication between sensors is carried out through using a radio communication. WSNs are employed in various applications requiring the use of fixed nodes (military applications) or mobile nodes (medical applications). In this paper,...
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...
A mobile Ad-hoc Network (MANET) become the one of top area of research, due to their simplicity of deployment. No infrastructure is required for nodes to connect with each other in the network, and with out aid of centralized administration. The nodes with MANET are quickly deployable, independent and self repair. Despite these advantages routing protocols suffering from many problems like mobility,...
