Two-way Time-of-Arrival (TOA) distance-ranging is well-suited for use in IEEE 802.11 MANETs and wireless mesh networks because it is simple, efficient and does not require precise time synchronization between network stations. Despite its utility we show that this distance-ranging procedure is completely insecure and demonstrate how it can be subverted by a simple but highly effective attack. This...
Wireless Web services, also called mobile services or M-services, provide access to Web services through wireless networks. In this paper, we propose novel access methods and multi-channel organization for mobile users to effectively access composite M-services in wireless broadcast networks. We define a few semantics for accessing broadcast based M-services and study their impact on access efficiency.
Traditionally, every mobile station (MS) riding in the mobile vehicle uses conventional connection to the base station (BS). However, in 802.16j mobile multihop relay (MMR) networks, one of the studied usage model is ldquocoverage on mobile vehiclerdquo. Therein, a relay station (RS) is mounted on a vehicle. The RS provides service to MSs riding on the vehicle by relaying their data to the mobile...
Simulating human mobility is important in mobile networks because many mobile devices are either attached to or controlled by humans and it is very hard to deploy real mobile networks whose size is controllably scalable for performance evaluation. Lately various measurement studies of human walk traces have discovered several significant statistical patterns of human mobility. Namely these include...
Among different techniques that provide mobile positioning, using the Received Signal Strength (RSS) is regarded as a low-cost solution which is applicable in a wide range of wireless networks. In this paper, we propose a cooperative RSS-based positioning algorithm that utilizes the additional RSS data of the short range communications between mobile stations (MSpsilas). We use a nonlinear least square...
Mobile Backbone Networks are heterogeneous wireless networks in which a subset of the nodes are more capable than others. The more capable nodes are referred to as Mobile Backbone Nodes (MBNs), whose primary role is to provide a mobile infrastructure in order to facilitate reliable end-to-end communication between nodes in the Network. In this paper, we consider the problem of optimally placing the...
