Mobile wireless networks offer numerous possibilities for applications in the current society. Since the radio transmitters become smaller, more and more mobile networks in which persons carry the mobile devices are developed. An example for such an network is given by a data communication network for soldiers or emergency workers, in which positions are exchanged in order to allow all persons ...

Network lifetime has become the key characteristic for evaluating sensor networks in an application specific way. Especially the availability of nodes, the sensor coverage, and the connectivity have been included in discussions on network lifetime. Even quality of service measures can be reduced to lifetime considerations. A great number of algorithms and methods were proposed to increase the l...

This paper investigates the problem of energy consumption in wireless sensor networks. Wireless nodes deployed harsh environment where conditions change drastically suffer from sudden changes link quality and node status. The end-to-end delay each varies due to variation On other hand, are supplied with limited it is a great concern extend network lifetime. To cope those problems, this proposes...

LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...

Wireless sensor networks (WSNs) are being envisioned for certain applications like habitat monitoring and environmental sensing. Wireless sensors are deployed to achieve network load balancing, prolonging network lifetime, and improving network coverage. To achieve these goals, energy estimation is one of the main constraints and concerns to consider, while deploying wireless sensors in a WSN f...

sensor networks generally consist of a very great number of sensor nodes which will be spread into a vast environment and aggregate data out of it. the sensor nodes are afflicted with some limitations as follows memory, reception, communication as well as calculation capability, and battery power. the transmission of a great amount of extra data increases data transmission and proportionally in...
