Energy Holes Avoiding Techniques in Sensor Networks: A survey
نویسنده
چکیده
This paper describes the concept of energy holes in sensor networks, their effects on network lifetime and various techniques to avoid them. The lifespan of sensor networks finish in short duration due to the presence of energy holes. A comparative study of strength and shortcoming of various techniques for combating energy holes problem has been discussed which shows that none of energy balanced protocol completely removes the energy holes from the sensor network. A non-uniform distribution of nodes towards the sink improves network lifespan. Keywords— Energy holes, Wireless sensor networks, uneven energy consumption.

Routing Hole Handling Techniques for Wireless Sensor Networks: A Review
A Wireless Sensor Network consists of several tiny devices which have the capability to sense and compute the environmental phenomenon. These sensor nodes are deployed in remote areas without any physical protections. A Wireless Sensor Network can have various types of anomalies due to some random deployment of nodes, obstruction and physical destructions. These anomalies can diminish the sensi...
متن کاملA 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 ...
