In this paper, we present a novel technique for localizing an event of interest in an underwater environment monitored by an underwater sensor network. The network consists of randomly deployed identical sensor nodes. Instead of proactively localizing every single node in the network as all proposed techniques set out to do, we approach localization from a reactive angle. We reduce the localiza...

In a ground anchor system, cables or tendons connected to a bearing plate are used for stabilization of slopes. Then, the stability of a slope is dependent on maintaining the tension levels in the cables. So far, no research on a strain-based field sensing system for ground anchors has been reported. Therefore, in this study, a practical monitoring system for long-term sensing of tension levels...

This specification defines a new mobility option, the IPv4 Traffic Offload Selector option, for Proxy Mobile IPv6. This option can be used by the local mobility anchor and the mobile access gateway for negotiating IPv4 traffic offload policy for a mobility session. Based on the negotiated IPv4 traffic offload policy, a mobile access gateway can selectively offload some of the IPv4 traffic flows...

In heterogeneous 5G networks (HetNets) a local anchor node ensures coordination among small cell low power nodes (LPNs). User equipment (UE) that cannot directly reach the local anchor node will transmit and receive data through LPN. To facilitate measurement of the interference power for this 2-hop hierarchical network topology, a total distance distribution between a UE and a local anchor is ...

Node localization in wireless sensor networks (WSNs) is one of the most important primary requisite that needs to be resolved efficiently as it plays a significant role in many applications namely environmental monitoring, routing and target tracking which is location dependent. Localization is defined as finding the physical co-ordinates of a group of sensor nodes. Localization is classified a...

Localization is crucial to many applications in wireless sensor networks. This article presents a range-free anchor-based localization algorithm for mobile wireless sensor networks that builds upon the Monte Carlo Localization algorithm. We improve the localization accuracy and efficiency by making better use of the information a sensor node gathers and by drawing the necessary location samples...

mobile-ad-hoc-networks (manets) are self-configuring networks of mobile nodes, which communicate through wireless links. the infrastructure of a mobile ad hoc network (manet) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. the main issues in manets include the mobility of the network nodes, the scarcity of computati...

Anchor-free localization algorithms do not depend on the existence of anchor objects. Since no anchor objects are required, the localization algorithm still can be applied in such problem as difficulty in distribution of anchor objects. In anchor-free localization problem, majority of the solutions need a specific requirement in order to achieve a high accuracy in their localization. In a real ...
