The proposed DRL is a distributed range-free localization approach. In order to save communication cost in localization, DRL reduces information flooding among nodes by dynamically changing each seed's flooding-hop to limit seed flooding in a local area; however, it still maintains the whole coverage. In addition, DRL allows all the nodes mobile and moving freely, while there is only a limited fraction...
We propose and formally characterize a new problem named the dynamic context coverage problem in capability-constrained mobile sensor network environments. The goal is to move and adjust a network of mobile sensors with limited sensing capabilities to quickly achieve good coverage of dynamic changing contexts and continuously maintain the level of coverage. We propose several self-organization strategies...
Although we can use telecomm technologies such as MMS to access various services, right now we do not have a good method to access several services at a time. In this paper, we propose a service-based P2P mobile sensor network (SPMSN) architecture. It allows users to adopt an integrated method to access various services even these services are not in the same physical network. An efficient communication...
