In this paper, we present Hierarchy-Based Anycast Routing (HAR), a routing protocol for collecting data over multi-hop, wireless sensor networks. The design of the protocol aims t...
Maximizing the aggregate network utility and minimizing the network energy consumption are important but conflict goals in wireless sensor networks. Challenges arise due to the app...
- Impact of random delays and losses in sensor networks manifests in the form of tardiness of data used for processing at the sink nodes. The age of data used by the end applicatio...
Wireless sensors use low power radio transceivers due to the stringent constraints on battery capacity. As a result, radio transmission with wireless sensors is unreliable. Furthe...
—Various sensor types, e.g., temperature, humidity, and acoustic, sense physical phenomena in different ways, and thus, are expected to have different sensing models. Even for th...
