“…Wireless ad hoc networks have emerged recently because of their potential applications in various situations such as battlefield, emergency rescue, and conference environments [1][2][3][4]. Ad hoc networks are without a fixed infrastructure; communications take place over a wireless channel, where each node has the ability to communicate with others in the neighborhood, determined by the transmission range.…”
Abstract. Previous work on energy efficient broadcast protocols for wireless ad hoc networks are based a commonly used physical layer model called "Pathloss model" which assume two nodes can communicate if and only if they exist within their transmission radius. In this paper, we analyze the effect of realistic physical layer on energy efficient broadcast protocols. We employ a more realistic log-normal shadowing model for physical layer and consider two link layer operating models: EER (end-to-end retransmission) and HHR (hop-byhop retransmission). Networks with omni-antennas and directional antennas are dealt with separately. Based on above models, we analyze how to adjust actual transmission radius for transmission nodes and relay nodes to get the trade-off between maximizing probability of delivery and minimizing energy consumption. From our analysis based on shadowing model, we have derived the appropriate transmission range. The results presented in this paper are expected to improve the performance of broadcast protocols under realistic physical layer.
“…In this paper, we propose a new self-organizing service provisioning infrastructure called Ad hoc Service Grid (ASG) based on MANET technology (Giordano, 2002). ASG fills the gap between small-scale WLAN access points and global-scale mobile phone networks and presents a promising approach to the problem of covering medium-scale locations with local services.…”
Abstract:The provisioning of location-specific services in medium-sized facilities like shopping malls, hospitals, and trade fares using WLAN access points or cellular phone systems has some drawbacks. It is rather inflexible or results in high running costs. We propose a new self-organizing infi-astructure called Ad hoc Service Grid (ASG) that is based on a mobile ad hoc network to resolve these issues. In this paper, we define the necessary concepts, structures and components for realizing ASGs. We present our approach to building a Serviceware that enables an AGS to self-organize. We evaluate the effectiveness of our mechanisms for service migration, replication, and lookup based on simulation results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
