Modified Bully Algorithm using Election Commission

2010

Electing leader is a vital issue not only in distributed computing but also in communication network [1, 2, 3, 4, 5], centralized mutual exclusion algorithm [6, 7], centralized control IPC, etc. A leader is required to make synchronization between different processes. And different election algorithms are used to elect a coordinator among the available processes in the system such a way that there will be only one coordinator at any time. Bully election algorithm is one of the classical and well-known approaches in coordinator election process. This paper will present a modified version of bully election algorithm using a new concept called election commission. This approach will not only reduce redundant elections but also minimize total number of elections and hence it will minimize message passing, network traffic, and complexity of the existing system.

Improved Bully Election Algorithm for Distributed Systems

Electing a leader is a classical problem in distributed computing system. Synchronization between processes often requires one process acting as a coordinator. If an elected leader node fails, the other nodes of the system need to elect another leader without much wasting of time. The bully algorithm is a classical approach for electing a leader in a synchronous distributed computing system, which is used to determine the process with highest priority number as the coordinator. In this paper, we have discussed the limitations of Bully algorithm and proposed a simple and efficient method for the Bully algorithm which reduces the number of messages during the election. Our analytical simulation shows that, our proposed algorithm is more efficient than the Bully algorithm with fewer messages passing and fewer stages.

A new approach of bully election algorithm for distributed computing

International Journal on Emerging Technologies, 2010

Many distributed algorithms require one process to act as a unique process to play a particular role in distributed systems. Election algorithms are meant for electing such a process called coordinator from among the currently running processes of distributed systems in such a manner that at any instance of time there will be a single coordinator for all the processes in the system. So, election algorithms are extremely crucial in any distributed system. Bully algorithm is one of the classical approaches for electing the coordinator in distributed systems. In this paper, we have presented an efficient version of bully algorithm to minimize the redundancy in electing the coordinator, to reduce the recovery problem of a crashed process in distributed systems and thus to maximize the effectiveness of traditional bully algorithm.

Co-Leader Based Leader Election Algorithm in Distributed Environment

In a distributed environment, several independent nodes work together by exchanging messages to each other. To achieve synchronization and co-ordination among the nodes, there is a need to elect one leader node. Previously several algorithms have been proposed,one of the classical and well-known algorithms to elect the leader node is bully algorithm. Ring algorithm is another modified version of bully algorithm. But these algorithms are having a large number of messages during election process. Till now several amendments are done over the bully algorithm to reduce the number of messages in the leader election process. This paper presents the concept of co-leader based leader election mechanism by which the number of messages can be greatly reduced and hence can reduce network traffic. Further, we have evaluated the performance of our proposed approach by considering the testbed of 10, 100 and 1000 nodes and shown the comparative analysis.

A New Approach for Election Algorithm in Distributed Systems

2009 Second International Conference on Communication Theory, Reliability, and Quality of Service, 2009

Leader election is an important problem in distributed computing systems. In this problem, when the leader is crashed, other nodes must elect another leader. Garcia-Molina's Bully Algorithm is a classic solution to cope with this problem. In this paper we introduce a new method based on electing a leader and alternatives. If the leader crash, the alternative takes, care of the leader's responsibilities. Our results revealed that often, after a leader crash, leader alternative elect as a leader and continue to work. increases. We show that our proposed algorithm is more efficient than the Garcia Molina's one in term of time, message complexity and in the fewer stages.

An Efficient Approach of Election Algorithm in Distributed Systems

In this paper, I have proposed an election algorithm that can be used in distributed systems to elect a coordinator. This is a betterment of an already existing Election algorithm (also known as Bully Algorithm) proposed by Hector Garcia-Monila (1982).The proposed algorithm is an efficient approach than Bully Algorithm.
