Wireless sensor networks with single sink node have some disadvantages. One example is that certain sensors near the sink or on critical paths consume energy much faster than other nodes. To solve such energy hole problem, we propose an Energy-efficient Multi-sink Clustering Algorithm (EMCA). In EMCA, each cluster head is selected based on the residual energy. We also design an inter-cluster an...

This paper presents a comprehensive survey of routing techniques in wireless sensor networks (WSN) and studies the advantages and performance issues of routing techniques with tradeoffs between energy and communication overhead savings. Based on the underlying network structure WSN routing algorithms can be categorized in flat, hierarchical, and location-based routing algorithms.

In WSNs, energy efficiency and low latency are considered as two key issues in designing routing protocol. This paper introduces two schemes to combine clustering strategy with chain routing algorithm in order to satisfy both energy and delay constraints in WSNs. Furthermore by one scheme, we propose a two layer hierarchical routing protocol called Chain Routing Based on Coordinatesoriented Clu...

In recent years, wireless sensor network (WSN) is a rapidly evolving technological platform with tremendous and novel applications. Many routing protocols have been specially designed for WSN because the sensor nodes are typically battery-power. To prolong the network lifetime, power management and energy-efficient routing techniques become necessary. In large scale wireless sensor networks, hi...

The decisions made by admission control algorithms are based on the availability of network resources viz. bandwidth, energy, memory buffers, etc., without degrading the Quality-of-Service (QoS) requirement of applications that are admitted. In this paper, we present an energy-aware admission control (EAAC) scheme which provides admission control for flows in an ad hoc network based on the know...

Saving power while ensuring acceptable service levels is a major concern in wireless sensor networks, since nodes are usually deployed and not replaced in case of breakdown. Several efforts have recently led to the standardization of a routing protocol for low power and lossy network. The standard provides various metrics, which can be used to guide the routing. Most protocol implementations us...

This paper presents the realistic approach towards the quantitative analysis and simulation of Energy Efficient Hierarchical Cluster (EEHC)-based routing for wireless sensor networks. Here the efforts have been done to combine analytical hardware model with the modified EEHC-based routing model. The dependence of various performance metrics like: optimum number of clusters, Energy Consumption, ...
