A location-based reliable multicast algorithm for mobile ad hoc networks is proposed in this paper. A grid network with geographical location information is divided into a high-channel subnetwork and a low-channel subnetwork according to labels of grids. Then destination nodes are partitioned into groups by using location information, the multicast routing is done in label order for each group. The...
The RFID and positioning system technologies are the key enablers for logistics supply chain visibility and tracking. While RFID is useful for inventory and material handling processes in warehouses, as soon as the RFID-tagged goods leave the warehouses, one often lose track of them until the next loading docks. In-between the sending and receiving points, there is often no tracking of the cargo which...
There are many activities that people prefer/opt out attending and these events are announced for attracting people. An intelligent recommendation system can be used in a social networking site in order to recommend people according to content and collaboration assessment. This study is an effort to recommend events to users within a social networking site. It can be any networking environment. We...
One of the key problems for wireless sensor networks (WSNs) is how to make the best of limited energy. The conventional clustering method has the unique potential to be the framework for energy-conserving wireless sensor networks .In this paper, a novel dynamic clustering algorithm based on geographical location information(GL-DC)is proposed for WSNs. Comparing with other algorithms, GL-DC has two...
To improve the efficiency of reliable broadcast/multicast MAC protocol in wireless multi-hop network, a location aid algorithm to eliminate redundant nodes was brought forward. Using the neighbor geographical location information, according to the principle of equivalent collision region, the algorithm could reduce redundant nodes from receivers, which is unnecessary for acknowledgement. Thus, the...
Geographic routing has been considered as an energy efficient and simple routing protocol for wireless sensor networks. It utilizes only geographical location information without global network structures to route data packets. To take these advantages of geographic routing, a source node should be aware of the location of a sink node. Methods that the source node efficiently obtains the sink location...
This paper introduces our network middleware for a new network where the address format includes geographical location information. The new address format compatible to IPv6 can quickly and easily provide location information of nodes of interest, and many new services/applications are possible without extra cost. A few representative functions of the middleware are defined and devised, and simulation...
Routing algorithms with low overhead, stable link, and the independence of large network are essential for the design and operation of the large scale wireless mobile ad hoc networks (MANET). In this paper, we proposed a novel cluster based location-aware routing protocol for large scale heterogeneous MANET (CBLARHM). There are two important mechanisms used in the CBLARHM to improve the MANET performance...
Energy balancing routing (EBR) is an efficient strategy to prolong the lifetime of wireless sensor networks (WSNs). In this paper, the network lifetime of minimum energy routing (MER) and energy balancing routing of multi- hop multi-to-one WSN is analyzed. A localized energy balancing routing (LEBR) algorithm is proposed. LEBR combines power control with routing based on geographical location information...
Support of ubiquitous roaming in fourth generation or beyond third generation (4G/B3G) networks (M.R. Kibria et al., 2005) will require accurate vertical handoff prediction in order to reserve resources in neighboring cells and to keep the handoff call dropping probability within an acceptable level. However with random terminal mobility and different cell structures (e.g. microcells, macrocells),...
