Wireless sensors networks (WSNs) are traditionally composed of large number of low-cost and tiny homogenous sensors nodes connected through a wireless network that gather data to be treated locally or relayed to the sink node through multi-hop wireless transmission. Moreover, such issues are very critical due servers resources constraints like efficient(More)
The advent of smart devices and continuous expansions of smart environments make Wireless sensor networks (WSNs) an important part of our daily lives. The usage of a myriad of devices in self-organizing networks in a various fields such as home monitoring, medical and military etc. requires an efficient delivery of sensed information. For this necessity, a(More)
One of the main pervasive problems Wireless Sensor Networks (WSN) encounter is to maintain flawless communication sharing and cooperative processing between sensors via radio links to ensure a reliable treatment of information. Many applications based on these WSNs consider local clocks at each sensor node that need to be synchronized to a common notion of(More)
Wireless sensor Networks (WSNs) contains a large amount of tiny and low value sensor nodes powered by tiny non reversible batteries and furnish with numerous sensing devices. The cluster-base technique is one among the nice perspectives to reduce energy consumption in WSNs. The lifespan of WSNs is maximized by using the uniform cluster location and leveling(More)
The clustering algorithm is one of technique used to reduce energy consumption. It can increase the lifetime and the scalability. Energy-efficient protocols should be designed for the characteristic of heterogeneous wireless sensors networks. In PC-LEACH, the cluster-heads are elected by a probability based on the min distance between node and base station.(More)
Energy consumption is an important parameter in the context of the wireless sensor networks (WSNs). Several factors can cause energy over consumption such as mobility, node position (relay or gateway), retransmissions... In this paper, we described a new Energy-Degree Distance(EDD) Clustering Algorithm for the WSNs. A node with higher residual energy,(More)
Wireless sensor network (WSNs) comprises of base station and number of nodes. Sometimes remote sensors are used which are generally known as remote sensor actuator systems. WSN is a large network of sensor nodes and these nodes are directly interacting with the environment by sensing the physical and ecological parameters like temperature, weight and so on.(More)
Development of wireless sensor network technologies have presented a availability of tiny sensor nodes along with the ability regarding sensing various physical as well as atmospheric circumstances, data handling and wireless communication. A number of detecting abilities affect the abundance application zones. On the other hand, a function associated(More)
