efficiency of the existing protected areas network in conservation of biodiversity is one of the most important challenges of protected areas custodians. despite there are numerous articles on evaluating the efficiency of the protected areas for conserving the habitat and species on national and international scales, in iran this subject has not been studied yet. the aim of the present study is...

The critical issue in sensor networks is the search of balance between the limited battery supply and the expected longevity of network operations. Similar goals exist in providing a certain degree of sensing coverage and maintaining a desirable number of sensors to communicate under the energy constraint. We propose a novel sensor network protocol, called Coverage-Aware Sensor Engagement (CASE...

In energy-limited wireless sensor networks (WSN’s), optimized node scheduling is an important technique for maximizing coverage and network lifetime. Existing coverage protocols present periodical, random and conditional node scheduling based on some coverage metrics. However, these scheduling techniques causes the frequent and un-necessary wake-ups of sleeping nodes which would increase the en...

Maintaining effective coverage and extending the network lifetime as much as possible has become one of the most critical issues in the coverage of WSNs. In this paper, we propose a multi-objective coverage optimization algorithm for WSNs, namely MOCADMA, which models the coverage control of WSNs as the multi-objective optimization problem. MOCADMA uses a memetic algorithm with a dynamic local ...
