Modified location aided routing protocol for UWB manets
… on the characteristics of UWB technology. The LocationAided Routing protocol scheme 1 (LARI) was first considered in order to satisfy therequirements of the proposed routing protocol which combines the advantages of the requestzone in LAR and the dynamic extended zones in the modified schemes …

A Location-aided Decision Algorithm for Handoff Across Heterogeneous Wireless Overlay Networks
… of environments described above. Therefore, a location-aided handoff decision algorithm was developed to prevent the triggering of handoffs that result from short visits to discovered WLAN's coverage area. The algorithm includes a location-based evaluation that runs on the network side and …

Optimizing ad-hoc on-demand distance vector (AODV) routing protocol using geographical location data
… thesis summarizes the body of research regarding location-aided routing protocols for mobile ad-hoc networks (MANET). This study focuses on the use of geographical location information to reduce the control traffic overhead caused by the route discovery process in the ad-hoc on-demand distance …

Fundamental Analyses of Collaborative and Noncollaborative Positioning
Determining the locations of devices in mobile ad-hoc networks (MANETs), wireless sensor networks (WSNs), and cellular networks has many important applications. In MANETs, which are useful in disaster recovery, rescue operations, and military communications, location information is used to enable …

Coexistence of Wireless Networks for Shared Spectrum Access
… in cognitive radio (CR) networks and geolocation database services in database-driven spectrum sharing. The second problem is the main focus of this dissertation. To obtain a clear picture of coexistence issues, we propose a taxonomy of heterogeneous coexistence mechanisms for shared …

Location-Aware Protocols for Energy-Efficient Information Processing in Wireless Sensor Networks
… node is often useful only in the context of the location of the data source. Thus, sensor networks rely on localization schemes to provide location information to sensor nodes. The premise of this thesis is that location-aware protocols, which are based on the assumption that sensor nodes can …
