Analysis and Evaluation of anEnergy-Efficient Routing Protocol for WSNsCombining Source Routing and MinimumCost Forwarding

Abstract

Source routing (SR) minimum cost forwarding (MCF)-SRMCF-is a reactive, energy-efficient routing protocol proposed to improve the existent MCF methods utilized in heterogeneous wireless sensor networks (WSN). This paper presents an analytical analysis with experimental support that demonstrates the effectiveness of the proposed protocol. SRMCF stems from SR concepts and MCF methods exploited in ad hoc WSNs, where all unicast communications (between sensor nodes and the base station, or vice versa) use minimum cost paths. The protocol utilized in the present work was updated and now also handles link and node failures. Theoretical analysis and simulations show that the final protocol exhibits better throughput and energy consumption than MCF. Memory requirements for the routing table in the base station are also analyzed. Experimental results in a real scenario were obtained for implementations of both protocols, MCF and SRMCF, deployed in a small network of TelosB motes. Results show that SRMCF presents a 33% higher throughput and 24% less energy consumption than MCF. Extensive

An Energy-Efficient Data Routing in Weight-Balanced Tree-Based Fog Network

“…3 that the proposed weight-balanced tree-based architecture in fog network results towards the fixed-(or almost fixed)sized routing table. It was already analysed and presented in [16] that the fixed (or almost fixed) routing table helps towards the design simplicity and reduced time for processing. For this reason, proposed architecture enables simple design and fast processing.…”

“…It is already presented that the execution time is always shorter for data transmission using a fixed length routing table over data transmission using a variable length routing table [16]. Hence, the said span of time t for data transmission in Eq.…”

“…An enhanced tree-based approach involving weight-balanced k -ary tree-based architecture towards data transmission in fog network was presented in this research, and its advantages were explored further. It was explored that proposed approach is benefited with fixed (or almost fixed) length routing table which further ensured a simple routing table and its fast processing [16]. Further it was analysed that faster execution of fixed (or almost fixed) length routing table facilitates low energy consumption in view of data transmission.…”
