Detailed explanation-1: -Low-energy adaptive clustering hierarchy ("LEACH") is a TDMA-based MAC protocol which is integrated with clustering and a simple routing protocol in wireless sensor networks (WSNs).
Detailed explanation-2: -Depending on the protocol operation, the hierarchical-based routing protocols are divided into negotiation-based, query-based, multipath-based, coherent-based, and QoS-based routing.
Detailed explanation-3: -SPIN PROTOCOL. It transfers all the useful data only from each node to every node in the network assuming that all the nodes in the network are Base Station. SPIN node uses three types of messages for communication. ADV-It is used to advertise new data. REQ-REQ is used to receive the actual data.
Detailed explanation-4: -At LEACH, processing of data occurs in specific nodes called cluster headers, and finally collected data move to the sink node. While in PEGASIS, no data collection occurs. LEACH is cluster-based hierarchy while PEGASIS is a string-based approach.
