3D Path Planning Algorithm for Mobile Anchor-Assisted Positioning in Wireless Sensor Networks
Positioning service is one of Wireless Sensor Networks’ (WSNs) fundamental services. The accurate position of the sensor nodes plays a vital role in many applications of WSNs. In this paper, a 3D positioning algorithm is being proposed, using mobile anchor node to assist sensor nodes in order to estimate their positions in a 3D geospatial environment. However, mobile anchor node’s 3D path optim...
متن کاملVertical Handover Management for VoIP Session over Broadband Wireless Networks
Today, wireless LAN (IEEE802.11g/n) has been the dominant wireless network that can provide high data rates in a limited coverage area. While emerging mobile WiMAX (IEEE802.16e) can provide a wireless broadband access to mobile users in a wide coverage area. These two different technolgies will co-exist while complementing each other in some regions, hence, a mobile node (MN) with dual interfac...
متن کاملRepresenting a Model for Improving Connectivity and Power Dissipation in Wireless Networks Using Mobile Sensors
Wireless sensor networks are often located in areas where access to them is difficult or dangerous. Today, in wireless sensor networks, cluster-based routing protocols by dividing sensor nodes into distinct clusters and selecting local head-clusters to combine and send information of each cluster to the base station and balanced energy consumption by network nodes, get the best performance ...
متن کاملCoexistence goals of VoIP and TCP traffic in mobile WiMAX networks: Performance of flat architecture
WiMAX IEEE802.16e standard is proposed as an attractive wireless communication technology for providing broadband access. For the network and application-level capacity and performance analysis, we first provide a short overview on mobile WiMAX networks, and then describe mobile WiMAX PHY and MAC layer. Afterward we present and discuss the benefits and challenges of flat architecture for mobile...
