MANET is very hostile environment to design and implement computing algorithms. One of the major concerns in MANET's is to elect a coordinator in order to manage many mobile computing applications. In the contemporary literature, many protocols exist for leader election. However, most of them use message broadcast technique. The present article proposes a technique that avoids the broadcast of messages...
Infrastructure investment decisions consider future infrastructure demand projections from freight models, the quality of which depends on fidelity of input freight data. The Freight Analysis Framework Version 2.2 (FAF2.2) being a primary source of freight data for infrastructure planning provides commodity origin-destination flows for 114 zones within the USA. Freight disaggregation approaches using...
This study examines multi-national data from Finland, Korea, the United States, Taiwan and Singapore to identify the factors that determine the purchase intention of mobile data services (MDS) and new mobile devices. A hybrid model incorporating factors from the means-end chain and cost-benefit equilibrium is tested on 3184 data with structural equation modeling. The results suggest that among the...
We propose a four-layer architecture model (FLAM) to obtain the potential energy savings for sensor nodes in large scale wireless sensor networks. The very first layer, the bottom layer is a network of a resource-constrained sensor nodes deployed in the field. The second layer is ad hoc network formed by resource-rich dynamic sink nodes, also knows as cluster sink nodes. The third layer consists of...
We illustrate the effective use of ATIM (ad hoc traffic indication message) window in static sensors to obtain potential energy savings for sensors during data dissemination in wireless sensor networks. The network consists of resource-rich mobile sink node and resource-constrained sensor nodes forming a square grid. Sink may be multihop away from the sensor nodes and in order to collect the data,...
We propose a three-layer architecture model (TLAM) for wireless sensor networks. The first layer (bottom layer) consists of a network of resource-constrained sensor nodes deployed in the field. The second layer contains a set of resource-rich dynamic sink nodes forming an ad hoc network. The sinks at layer second are responsible to monitor and collect data from a region, called cluster. So the sinks...
Mobile ad hoc networks remove the dependence on a fixed network infrastructure by treating every available mobile node as an intermediate switch, thereby extending the range of mobile nodes well beyond their base transceivers. Since routing is the backbone of any mobile ad hoc communication, thus if there occur any flaws in the routing, the whole of the communication would come down to a stand still...
This paper presents modification of span for wireless mobile ad hoc networks. Span is an energy efficient coordination algorithm for topology maintenance in wireless ad hoc networks. Each node in span does the local decision on whether to announce for or withdraw from coordinator. We modify coordinator withdrawal procedure of span by adding average speed of node as one of the condition for withdrawing...
