In this paper, we propose a combination between a routing protocol Greedy Perimeter Stateless Routing (GPSR) and Hierarchical Location Service (HLS) that we denote Hybrid Hierarchical Location Service (HHLS). HLS and GPSR used to be combined in the original work with a direct method, i.e. GPRS takes care of routing packets and HLS is called to get the(More)
Nodes in VANETs move at high speed. This high mobility makes most conventional routing protocols incompatible with this type of network. A new class of geographic routings has emerged. Most of these routing protocols suppose that the nodes position is known in advance and that the nodes do not have time to move significantly between sending packets and(More)
Treating roads in winter (snow removal for example) is an important service that facilitates people's movement and increases the pavement's life. However, these treatments can be very expensive and inefficient if they are not properly scheduled. For this purpose, a complete view of the pavement's state is often essential for the management and the(More)
Recently, the topology control strategies attract more and more the research community as being a crucial issue to be handled for the Wireless sensors networks (WSNs). In this paper, we propose a centralized power control mechanism based on the link gain information to reduce network energy consumption. Our mechanism works through two steps, first we(More)
