Toward Broadcast Reliability in Mobile Ad Hoc Networks with Double Coverage. (A New TCP for Persistent Packet Reordering).

Abstract:

The broadcast operation, as a fundamental service in mobile ad hoc networks (MANETs), is prone to the broadcast storm problem if forwarding nodes are not carefully designated. The objective of reducing broadcast redundancy while still providing high delivery ratio under high transmission error rate is a major challenge in MANETs. In this paper, we propose a simple broadcast algorithm, ca ....etc

Abstract

The emergence of coverage holes in wireless sensor networks (WSNs) means that some special events have broken out and the function of WSNs will be seriously influenced. Therefore, the issues of coverage holes have attracted considerable attention. In this paper, we focus on the identification of boundary nodes and coverage holes, which is crucially important to preventing the enlargement of coverage holes and ensuring the transmission of data. We define the problem of coverage holes and propose two novel algorithms to identify the c ....etc

The Coverage Problem in a Wireless Sensor Network


ABSTRACT
One fundamental issue in sensor networks is the coverage problem,
which reflects how well a sensor network is monitored or tracked
by sensors. In this paper, we formulate this problem as a decision
problem, whose goal is to determine whether every point in
the service area of the sensor network is covered by at least k sensors,
where k is a predefined value. The sensing ranges of sensors
can be unit disks or non-unit ....etc

Communication Coverage
in Wireless
Passive Sensor Networks


Abstract

System lifetime of wireless sensor networks (WSN) is inversely proportional to the energy consumed by critically energy-constrained sensor nodes during RF transmission.
Hence, wireless passive sensor networks (WPSN) designed to operate using MB do not have the lifetime constraints of conventional WSN.
However, the communication performance of WPSN ....etc

Abstract We are interested in the sensor networks for scientific applications to cover and measure statistics on the sea surface. Due to flows and waves, the sensor nodes may gradually lose their positions; leaving the points of interest uncovered. Manual readjustment is costly and cannot be performed in time. We argue that a network of mobile sensor nodes which can perform self-adjustment is the best candidate to maintain the coverage of the surface area. In our application, we face a unique double mobility coverage problem. That is, there is ....etc

Efficient Broadcasting with Guaranteed Coverage in Mobile Ad-Hoc Networks at vb.net

Abstract:
We study an efficient broadcast scheme in mobile ad hoc networks (MANETs). The objective is to determine a small set of forward nodes to ensure full coverage. We first study several methods that guarantee coverage when the local view of each node on its neighborhood information is updated in a timely manner. Then we consider a general case where nodes move even during the broadcast process, making it impractical to maintain up-to-date and c ....etc

In this text, a simple and fast deterministic solution to the area coverage problem in wireless sensor networks has been described. The method is to is determine whether all points in a region are covered by a given set of sensors, where each sensor may have any arbitrary sensing shape. the area coverage problem is translated into the intersection points' coverage problem - simpler and more suitable for evaluating the area coverage problem.

Abstract Deriving the proper density to achieve the region coverage for random sensors deployment is a fundamentally important problem in the area of wireless sensor networks. Most existing works on sensor coverage mainly concentrate on the two-dimensional (2D) plane coverage which assume that all the sensors are deployed on an ideal plane. In contrast, sensors are also deployed on the three-dimensional (3D) rolling surfaces in many real applications. Toward this end, we study the coverage problem of wireless sensor networks for the rolling te ....etc

Coverage in hybrid mobile sensor networks-IEE TRANSACTIONS ON MOBILE COMPUTING, VOL. 7, NO. 11,8-glomosim


Abstract This paper considers the coverage problem for hybrid networks which comprise both static and mobile sensors. The mobile sensors in our network only have limited mobility, i.e., they can move only once over a short distance. In random static sensor networks, sensor density should increase as O(logL+ k log logL) to provide k-coverage in a network with a size of L. As an alternative, an all-mobile network can provide k-c ....etc
