Lack of infrastructure, Route discovery management and Energy consumption monitoring in MANET poses very big challenges for researchers working in this field. The existing protocols like Link State Routing, Destination Sequence Distance Vector, Low Energy Adaptive Cluster Hierarchy and Parno Luk Gaustad Perrig (PLGP) are not well suited for decentralized schemes because of the energy constraint...

In Mobile Ad Hoc Network (MANET), resources are limited and valuable. Battery power is a sensitive resource, it is limited due to the relatively small size of the mobile nodes. Managing this limited resource with the current battery manufacturing techniques is a key challenge in MANET environment. In order to achieve scalability in MANET, hierarchical solutions are adopted like the cluster-base...

In hierarchical networks, nodes are separated to play different roles such as CHs and cluster members. Each CH collects data from the cluster members within its cluster, aggregates the data and then transmits the data to the sink. Each algorithm that is used for packet routing in quality of service (QoS) based applications should be able to establish a tradeoffs between end to end delay paramet...

Reducing the energy consumption of available resources is still a problem to be solved in Wireless Sensor Networks (WSNs). Many types of existing routing protocols are developed to save power consumption. In these protocols, cluster-based routing protocols are found to be more energy efficient. A cluster head is selected to aggregate the data received from root nodes and forwards these data to ...

In our previous work, a highly scalable and faulttolerant network architecture, the Progressive Multi-hop Rotational Clustered (PMRC) structure, is proposed for constructing large-scale wireless sensor networks. Further, the overlapped scheme is proposed to solve the bottleneck problem in PMRC-based sensor networks. As buffer space is often scarce in sensor nodes, in this paper, we focus on stu...

Clustering is an efficient technique that is widely adopted in wireless sensor networks. It divides network into clusters and let cluster heads be responsible for forwarding aggregated data to the sink. With energy efficiency in account, the conflict between an individual node and the entire network remains to be solved. In this paper, we propose a Density-based Energy-efficient Game-theoretic ...

Abstract This paper suggests an algorithm which increases the energy efficiency based on LEACH (Low Energy Adaptive Clustering Hierarchy)[1] for sensor network routing. Due to the random cluster head election process, LEACH does not guarantee the optimization for the number and position of cluster heads. Also it results in inefficiency in energy consumption. This paper suggests improved cluster...

Secure and accurate data fusion is an important issue in wireless sensor networks (WSNs) and has been extensively researched in the literature. In this paper, by combining clustering techniques, reputation and trust systems, and data fusion algorithms, we propose a novel cluster-based data fusion model called Double Cluster Heads Model (DCHM) for secure and accurate data fusion in WSNs. Differe...

Wireless Ad-hoc networks are distributed systems that often reside in error-prone environments. Self-stabilization lets the system recover autonomously from an arbitrary system state, making the system recover from errors and temporarily broken assumptions. Clustering nodes within ad-hoc networks can help forming backbones, facilitating routing, improving scaling, aggregating information, savin...

Communication in mobile ad hoc networks (MANET) without having any fixed infrastructure has drawn much attention for research. The infrastructure based cellular architecture sets up base stations to support the node mobility. Thus, mapping the concepts of base stations into MANET could meet its challenges like limited battery power, scalability, available bandwidth etc.. This leads to the desig...
