Wireless technologies gained great popularity for the past two decades. Laptop and smart phones are some wireless devices and being essential for our daily lives. Wireless Adhoc Network(WANET) or Mobile Adhoc Network(MANET) is a decentralized type of Wireless Network whereas mobile nodes joined without having any pre-established infrastructure or any other kind of fixed stations. Due to this nature of mobility and lack of authorization facilities, MANET may compromise by any malicious activities easily. Therefore handing over reliable and efficient data transfer is very crucial. Clustering is a process where nodes are divided into several groups as to increases scalability and to decreases network overhead. This paper proposed an algorithm namely Weight Based Clustering Algorithm (WBCA) towards to form reliable clusters of trusted nodes only as to sustain stability and flexibility of the network. Experiment results expose that the proposed clustering algorithm produces reliable clusters than Weight Clustering Algorithm (WCA) over some set of simulation scenarios.
