Mobility management in Wireless Sensor Networks (WSNs) is a complex problem that must be taken into account in all layers of the protocol stack. But this mobility becomes very challenging at the MAC level in order to do not degrade the energy efficiency between sensor nodes that are in communication. However, among medium access protocols, sampling(More)

This paper explores the use of mobile Geographic Information System (GIS) computing in its application in water point management. Applications based on mobile GIS are the best way to provide appropriate solutions for rural populations such as breeders in Senegal. In fact, the breeders have many problems to find water points for their cattle group. So far,(More)
