Wireless Sensor Networks (WSNs) is used to sense the data and communicate with others by wireless. The nodes involved in this network consist of small and minimum powered. To process their function these nodes organised and configured itself. In recent year WSNs are used many applications due its features such as low cost, scalability, throughput, easy deployment, flexibility and efficiency. Even though it has best features lifetime of network and security of routing are stills challenges one in WSNs. These challenges exit because of insignificant cluster head (CH) selection and insufficient trust worthy path selection. So, it is necessary to analyse the various routing and cluster head selection techniques to proposed new methods to solve these challenges. This paper reviewed the various techniques like LEACH, LEACH-C, BO-LEACH, SMOTECP, PSO, DT, HAS, ESD, BCDCP of CH selection and routing methods based on some parameters such as methodology, contribution, existing methods used and result of their work. Finally, we produced analysis of various techniques based on the following parameter: energy consumption, throughput and lifetime.
