A mobile wireless sensor network owes its name to the presence of mobile sink or sensor nodes within the network. The advantages of mobile WSN over static WSN are better energy efficiency, improved coverage, enhanced target tracking and superior channel capacity. In this paper we present and discuss hierarchical multi-tiered architecture for mobile wireless(More)
Usually, sensor data needs to be disseminated from the source sensors to data collectors (e.g., sink nodes), making those spatially distributed sensor data available for applications to access. The widespread and ubiquitous nature of mobile devices, e.g., PDAs and cell phones around the world, makes them attractive to be used as mobile data collectors(More)
In the paper, a new range-boundary aware mobility-assisted localization(RAML) scheme is presented to make mobile sink identify the location of sensor nodes which are deployed in a random mode within a certain geographical area. Not like other localization techniques, the presented localization scheme works without any additional hardware and achieves better(More)
In P2P network, there are a considerable proportion of free riders, which contribute nothing or little to the P2P system but obtain resources from the system. In order to address this problem, we present a utility-based auction cooperation incentive mechanism in the P2P network. Our approach is that before communicating with destination peer, the source(More)
Based on a new range-boundary aware mobility assisted localization, we proposed a more energy efficient localization scheme which is called Time-adaptive range-boundary aware mobility-assisted localization (TRAML) to decrease the number of the transmitted packets from the point view of both the sink and the nodes. Noticed that the sink will send the beacon(More)
