Two of the main issues in wireless industrial Internet of Things applications are interoperability and network lifetime. In this work we extend a semantic interoperability platform and introduce an application-layer sleepy nodes protocol that can leverage on information stored in semantic repositories. We propose an integration platform for managing the sleep states and an application layer protocol...
This paper reports our recent result in designing a function for autonomous APs to estimate throughput and delay of its clients in 2.4GHz WiFi channels to support those APs' dynamic channel selection. Our function takes as inputs the traffic volume and strength of signals emitted from nearby interference APs as well as the target AP's traffic volume. By this function, the target AP can estimate throughput...
In this paper we consider the 1-movable dominating set problem in wireless sensor networks (WSNs), motivated by applications of WSNs such as detection of environmental activity, surveillance, area monitoring and attaining small degree of fault tolerance in such applications. To find a minimum 1-movable dominating set is shown to be NP-complete. Hence, in this paper we design centralized and distributed...
