To measure the physiological parameter accurately, a plenty of sensors are placed in, on or around the human body, which form the Wireless Body Area Network(WBAN). But for energy saving, some sensors can be chosen to achieve the same goal. So an iterative convex optimization algorithm with constrained beam-pattern synthesis of sensor selection is proposed to solve this problem. In the optimization...
A novel application semantics based routing algorithm is proposed for wireless sensor networks to prolong network lifetime. The Sink node broadcasts task semantics message periodically in flooding fashion, the inter-network nodes process data at the different application task levels. According to semantic information of application and the node and its neighbors' status, the node processes data and...
Focusing on the problem of the poor locating performance in original DV- Hop algorithm which is one of the range-free algorithms in wireless sensor network (WSN), an intelligent DV- Hop algorithm for locating nodes was proposed in this paper. Fully considering the effect of dynamic topology, the self-adaptive artificial bee colony (SAABC) algorithm was introduced to estimate the unknown nodes location...
RBAC (Role Based Access Control) model was extended in theory and a special RBAC for wireless sensor network based on energy considerations was proposed. The core modules, levels of roles and restriction mechanisms are described and defined in detail for the model. For different wireless sensor network architectures, the appropriate mechanisms were designed. Finally, theoretical analysis and evaluation...
In wireless sensor network, all nodes are energy constrained and designing an energy efficient routing protocol is very important. Clustering routing protocol is a kind of energy efficient routing, while using a virtual backbone to organize the nodes and perform an efficient routing is also a feasible way.
