    A RSSI-Based Algorithm for Indoor Localization Using ZigBee in Wireless Sensor Network

    For the various applications in home automation, the service system requires to precisely estimate user's locations by certain sensors. It is considered as a challenge to automatically serve a mobile user in the house. However, indoor localization cannot be carried out effectively by the well-know Global Positioning System (GPS). In...

    A Fast and Memory Efficient Dynamic IP Lookup Algorithm Based on B-Tree

    The Internet consists of a mesh of routers interconnected by links. In a router, the major function in packet forwarding process is to lookup the destination addresses for the incoming packets according to the routing table. In the recent years, due to the prevalence of the World Wide Web (WWW)...

    A Novel Secure Communication Scheme in Vehicular Ad Hoc Networks

    Vehicular networks are very likely to become the most pervasive and applicable of mobile ad hoc networks in this decade. Vehicular Ad-hoc NETwork (VANET) has become a hot emerging research subject, but few academic publications describing its security infrastructure. In this paper, the authors review the secure infrastructure of VANET,...

    Using Vehicular Sensor Networks for Mobile Surveillance

    Mobile surveillance has been recently proposed as a replacement for traditional road-side surveillance system. One important aspect of a mobile surveillance system is to decide what are the events of interest. In this paper, the authors adopt the concept of participatory sensing for mobile surveillance by involving a human into...

    Using Simple Harmonic Motion to Estimate Walking Distance for Waist-Mounted PDR

    A huge body of work utilized signal strength of short range signal (such as WiFi, Bluetooth, ultra sound or Infrared) to build a radio map for indoor localization, by deploying a great number of beacon nodes in the building. The drawback of such an infrastructure-based approach is that the deployment...

    Decentralized Boundary Detection Without Location Information in Wireless Sensor Networks

    In Wireless Sensor Networks (WSNs) deployed in an outdoor environment, obstacles may occur as a result of a non-uniform distribution of the sensor nodes or the presence of barriers. These obstacles result in a degradation of the network performance, so obstacle identification is a major concern in most WSN applications....
