A Density Control Scheme Based on Disjoint Wakeup Scheduling in Wireless Sensor Network
نویسنده
چکیده
Since sensor nodes have limited battery power, it is desirable to select a minimum set of working sensor nodes which should be involved in sensing and forwarding data to the sink. In this paper, we propose a disjoint scheduling for density control in wireless sensor network to achieve the desired robust coverage as well as satisfactory connectivity to the sink with a small set of working nodes. Simulations showed that our scheme works well in an energy efficient fashion by turning off too many redundant nodes.

A JOINT DUTY CYCLE SCHEDULING AND ENERGY AWARE ROUTING APPROACH BASED ON EVOLUTIONARY GAME FOR WIRELESS SENSOR NETWORKS
Network throughput and energy conservation are two conflicting important performance metrics for wireless sensor networks. Since these two objectives are in conflict with each other, it is difficult to achieve them simultaneously. In this paper, a joint duty cycle scheduling and energy aware routing approach is proposed based on evolutionary game theory which is called DREG. Making a trade-off ...

In a wireless sensor networks, many topics have been studied in several filed. Most of them are concentrated on efficient use of energy to prolong the network lifetime. In a special environment like as remote battlefield, desert, forest, it is more difficult to recharging the battery of sensor. In this paper, we propose a density control method in a dense wireless sensor. We prolong the lifetim...
متن کاملA novel sleep/wakeup power management in wireless sensor network: A Fuzzy TOPSIS approach
The wireless sensor network (WSN) is typically comprised many tiny nodes equipped with processors, sender/receiver antenna and limited battery in which it is impossible or not economic to recharge. Meanwhile, network lifespan is one of the most critical issues because of limited and not renewal used battery in WSN. Several mechanisms have been proposed to prolong network lifespan such as LEACH,...

متن کاملHybrid Key pre-distribution scheme for wireless sensor network based on combinatorial design
Key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.Due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. To establish a secure communication, two nodes must share common key from their key-rings. Otherwise, they can find a key- path in which ens...
