Abstract: An efficient routing in Wireless Sensor Networks (WSNs) helps to utilize the network energy economically to escalate the lifetime of the network. PEGASIS is a forerunner for chain-based routing algorithm designed with aim to enhance network lifetime. But the algorithm suffers from problems like data redundancy, long link formations, large latency period and so on. Many researchers propounded the enhanced versions of PEGASIS to overcome one or more problems associated with it. This paper presents the literature survey of 45 such protuberant research papers spanning over last eighteen years to provide insight into the problems of chain-based routing algorithms. In this paper, an effort has been made to classify these chain-based routing algorithms for WSN based upon their features. The article dowries the strong and weak points of these enhanced versions proposed by each of fellow researchers. Such an exhaustive survey would surely be fruitful to provide more healthy and efficient solutions. Finally, some open issues concerning the future design of chain-based routing algorithms have also been presented.
