Item Performance comparison of MANET routing protocols(2010) Kumar, J.; Kulkarni, M.; Gupta, D.A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any existing infrastructure. Since not many MANETs are currently deployed, research in this area is simulation based. We have compared different routing protocols like DSR, DSDV, AODV to study the mobility characteristics of different scenarios in which MANETs may be deployed. Evaluation of the impact of different mobility models on the performance of these routing protocols is carried out, based upon different parameters-throughput, Packet delivery ratio, end to end delay, and offered traffic load. Also, mobility models are compared based on these performance parameters in various routing protocols. © 2010 Praise Worthy Prize S.r.l. - All rights reserved.Item Energy efficient routing protocols for wireless sensor networks: A survey(2011) Shivaprakasha, K.S.; Kulkarni, M.Wireless Sensor Networks (WSNs) have become one of the emerging trends of the modern communication systems. They find their applications in various fields like habitat monitoring, home automation, environment monitoring, battle field environment etc. WSNs are different from Mobile Adhoc Networks in the perspective of energy awareness, adaptive communication patterns and the routing algorithms. As the sensor devices are powered by batteries, which cannot be recharged often, the power awareness is one of the major requirements in WSNs. Many energy aware routing protocols have been proposed in the literature. In this survey, an attempt has been made to summarize the various energy aware routing protocols available in the literature and also a comparative analysis of these has been made considering various network parameters like the delay, routing overhead, QoS, type of routing protocol etc. © 2011 Praise Worthy Prize S.r.l. - All rights reserved.Item Range adjustable hybrid multi path routing algorithm for WSNs(Inderscience Publishers, 2017) Nishant, J.D.; Kulkarni, M.; Shivaprakasha, K.S.Node disjoint multipath routing is an effectiveway to achieve reliability and load balancing in wireless sensor networks (WSNs). In this paper, an attempt has been made in proposing a novel node disjoint multipath routing algorithm, the range adjustable hybrid multipath (RAHM). RAHM uses hybrid routing approach. The centralised node disjoint path selection is based on the objective of minimising the end to end communication drain on each path. The localised distributed route reconfiguration initiates on the node failure events and the route re-establishment is based on the objective of residual energy of the nodes. The performance of the proposed algorithm is validated through simulations and compared with collection tree protocol (CTP) and multipath ring routing protocol. RAHM performs around 36% and 76% better in terms of network lifetime parameter compared to CTP and multipath ring routing protocol respectively. © 2017 Inderscience Enterprises Ltd.
