High Performance Fault Tolerance Protocol for Mobile Distributed Systems
Gurdev Singh, Rohit Kumar Verma · 2013
A mobile computing system consists of mobile and stationary nodes, connected to each other by communication network. The system raises several constraints such as limited battery life, mobility, disconnection of hosts and lack of stable storage. To reduce the lost of computational work during recovery from the node failures periodic collection of a consistent snapshot of the system (checkpoint) is required. This paper presents an efficient coordinated checkpoint protocol which is non-blocking and not forces every node to take local checkpoint. We proposed that collected global snapshot is consistent. Our protocol meet the low energy consumption, reduces storage overhead having low communication and low band width constraints of mobile computing systems.
