The energy hole phenomenon has been a great hinderance in efficient performance of Wireless Sensor Networks (WSNs). In this paper, energy hole problem is addressed with reference to variable transmission range of sensor nodes and static number of Cluster Heads (CHs), which aggregate the data of their region and forward it to next CH or Base Station (BS). Network field is first divided into regions...
In Wireless Sensor Networks, efficient energy management is of great importance. In this paper, we propose a novel routing protocol, Threshold Sensitive Density Controlled Divide and Rule (TSDDR) to prolong network lifetime and stability period. To achieve these targets, we utilize static clustering with threshold aware transmissions. Simulations are done in MATLAB and the results show that our protocol...
To overcome energy hole problem unequal clustering structures have been proposed for the aim of network stability. Energy hole avoidance remains as a challenging problem. Hexagons are an ideal shape for uniform random deployment of nodes in Wireless Sensor Networks (WSN), because clusters areas are seamlessly divided by the hexagons. In addition, regular hexagons have largest coverage area and covers...
In Wireless Sensor Networks (WSNs) unbalanced energy consumption is a major problem. As a result, energy hole is created and network lifetime is reduced. In this paper, we propose IDDR to avoid the energy hole creation through uniform energy consumption. Proposed scheme reduces coverage and energy hole by dividing the network into small segments with static number of Cluster Heads (CHs) in each round...
Cluster based routing protocols for Wireless Sensor Networks (WSNs) have been widely used for better performance in terms of energy efficiency. Efficient use of energy is challenging task of designing these protocols. Energy holes are created due to quickly drain the energy of a few nodes due to nonuniform node distribution in the network. Normally, energy holes make the data routing failure when...
