In the opportunistic networks, nodes carry and store the data and forward it until they encounter each other. How to choose an appropriate opportunity to forward data is pivotal for nodes' routing in this type of networks. Since nodes currently will keep a regular movement state in the scene of this paper discussed, forecasting a node's moving track in the near future would be very helpful. Through...
Intermittent Connected Mobile Sensor Networks (ICMSN) have emerged in recent studies, e.g. underwater sensor networks, wildlife tracking and human-oriented flu virus monitoring. In these networks, conventional routing protocols in WSN are not suitable for data gathering application in ICMSN since packets will be dropped when no complete route to the sink is available. In this paper, we propose an...
In this article, we deal with the load balancing routing problem for wireless sensor network (WSN) in two-dimensional mesh. Load balancing routing is very important for the WSN. However the existing balancing routing algorithms mostly focus on the energy balance and most of them are based on clustering technology. It needs time and energy to construct clusters for clustering technology. We propose...
Opportunistic networks is one of the most interesting evolutions of mobile ad-hoc networks (MANETs). This paper describes a novel outdoor wireless localization approach. It includes the deployment and localization algorithm in Opportunistic networks. In this paper, the opportunistic networks model consists of static nodes and motes. The static nodes are location known but motes are location-unaware...
For the applications of Wireless Sensor Networks (WSN), the lifetime of WSN has been a very important and hot research topic. In practical applications, data gathering is a common but critical operation in many applications of WSNs, especially in environment monitoring system. In some harsh environment, deploying wireless sensor networks is a difficult and expensive work. Therefore, energy saving...
Virtual Screening (VS), a productive and cost-effective technology in quest for novel lead compounds, is a new approach in the pharmaceutical industry. This kind of applications belongs to the family of large scale loosely coupled parallel applications, whereas concurrent tasks are independent of each other, and are most suited to run on the Grid environments. However, there are some important practical...
A new broadcast protocol have been developed in this paper. Itpsilas based on a new method in which rebroadcasting a packet is decided by an intelligent classification scheme. Each MN builds a classifier and uses it on data collected from the network environment. For an input vector describing a broadcast packet and current network conditions, the classifier returns a result of "rebroadcast"...
