Enhanced Cluster Based Routing Protocol for MANETS

, 2012
Mobile ad-hoc networks (MANETs) are a set of self organized wireless mobile nodes that works without any predefined infrastructure. For routing data in MANETs, the routing protocols relay on mobile wireless nodes.

Fuzzy Clustering Algorithm for Enhancing Reliability and Network Lifetime of Wireless Sensor Networks

IEEE Access, 2020
To prolong the function of wireless sensor networks (WSNs), the lifetime of the system has to be increased. WSNs lifetime can be calculated by using a few generic parameters, such as the time until the death of the first node and other parameters ...

A Node Coverage Optimization Method for Strip Area in WSN [PDF]

Jisuanji gongcheng, 2020
In the process of deploying a strip area in a Wireless Sensor Network(WSN),the amount of data forwarded by the cluster head nodes is inversely proportional to its distance from the base station,which tends to cause uneven network load.Therefore,this ...

An ACO Algorithm for Effective Cluster Head Selection

, 2011
This paper presents an effective algorithm for selecting cluster heads in mobile ad hoc networks using ant colony optimization. A cluster in an ad hoc network consists of a cluster head and cluster members which are at one hop away from the cluster head.

ICIC: A Dual Mode Intra-Cluster and Inter-Cluster Energy Minimization Approach for Multihop WSN

IEEE Access, 2022
Energy minimization is one of the paramount issues in designing of the wireless sensor network and becomes more complex for multi-hop transmission. Furthermore, selection of multi hop route for the packets transmission is also a tedious task.
