Core network supported multicast routing protocol for wireless sensor networks

Abstract

Multicast routing protocols improve the network performance by optimising the parameters such as bandwidth, channel utilisation and throughput rate. In wireless sensor network, the primary multicast routing protocol is geographic multicast routing. This study proposes core network supported multicast routing (CNSMR) protocol, a stateful-based distributed multicast routing protocol for sensor networks. The proposed protocol comprises of heterogeneous nodes such as cluster head (CH) nodes, core nodes (CNs) and sensor nodes (SNs). The distinct set of nodes known as CNs have computing, storage and energy resources more than the SNs. CH nodes and CNs form the core network, and CNs with core network and SNs form the core network supported multicast tree. SNs participate in multicast routing supported by the core network and thus save the node energy. Multicast routing in the proposed core network supported multicast trees balance the load in the network and improve the network performance as compared to the existing WSN multicast routing protocols. The proposed CNSMR protocol is compared with the existing WSN multicast routing protocols such as DCME-MR, Intelligent-MR, H-GMR and OnDemand-MR. Simulation results indicate improvements in delay latency, energy save ratio, throughput rate, end-to-end packet delay, multicast control overhead ratio and packet delivery ratio for the proposed protocol.

Comparative analysis of energy based optimized dynamic source multipath routing protocol in WSNs

“…A new multicast routing protocol technique has been introduced by Maddali [14] which follows distributed mechanism using various routing states. Heterogeneous routing was the formal beneficiary of this technique and a new node named as core node has been used.…”

Investigation on different clustering techniques in wireless sensor networks

“…For direct communication, the CHs furthest away from the BS are the most critical nodes, whereas in multi-hop communication, the CHs closest to the BS are burdened with a heavy relay traffic load and die first. Therefore clustering and multi-hop communication are the most efficient routing schemes in WSNs to balance the relay traffic over the network and effectively overcome the path loss effects (Maddali, 2015). Figure 2 shows that decentralised data source architecture eliminates the single-point of failure.…”

Performance Chronicles of Multicast Routing Protocol in Wireless Sensor Network

“…Maddali [36] have introduced a unique multicast routing technique that adopts distributed mechanism using states of routing. The technique was originally made for heterogeneous routing and introduces a new node type called as core node.…”
