Ad-hoc sensor networks need to create their own network after deployment. Various
schemes have been suggested for sensors to create a better coverage pattern than if they …

Positioning disk-shaped sensors to optimize certain coverage parameters is a fundamental
problem in ad hoc sensor networks. The hexagon lattice arrangement is known to be …

It is well-known that placing disks in the triangular lattice pattern is optimal for achieving full
coverage on a plane. With the emergence of wireless sensor networks, however, it is now no …

An ad-hoc sensor network is composed of sensing devices which can measure or detect
features of their environment, communicate with one other and possibly with other devices …

In this paper we study the following problem: we are given a certain one-or two-dimensional
region R to monitor and a requirement on the degree of coverage (DoC) of R to meet by a …

In the literature of ad-hoc sensory networks, a wellstudied problem is that of achieving full
sensory coverage within a region according to the boolean model of coverage. We introduce …

Sensor networks pose a number of challenging conceptual and optimization problems such
as location, deployment, and tracking. One of the fundamental problems in sensor networks …

Extensive use of wireless sensor networks for various applications like surveillance, habitat
monitoring, battlefield etc., demand high probability of coverage and connectivity. The first …

Wireless ad-hoc sensor networks have recently emerged as a premier research topic. They
have great long-term economic potential, ability to transform our lives, and pose many new …

We are concerned with wireless sensor networks where n sensors are independently and
uniformly distributed at random in a finite plane. Events that are within a fixed distance from …
