This paper presents a novel approach for self-healing in cellular networks based on the application of mobile terminals context information: time, service, activity, identity and, especially, location. Context information is therefore used to support root cause analysis, providing improved network fault diagnosis compared to classical non-context-aware approaches. The integration of context information...
Node localization is one of the key technologies of WSN applications. In this paper, we propose a distributed weighted search-based localization algorithm (WSLA) and its refinement algorithm (WSRA) for wireless sensor network (WSN). In real applications, WSLA + WSRA need to run iteratively to achieve localization and position refinement of nodes. In each iteration of WSLA, every node obtains the coordinate...
