Balanceamento de carga baseado em divisão de tarefas multimídia para RSSF reativas

Abstract

This paper presents TDMEN, an innovative approach for Wireless Multimedia Sensor Networks (WMSNs) aimed at optimizing energy consumption and extending network lifetime. TDMEN applies a strategic task division, enabling local data processing and efficient energy balancing among devices. Two variations of TDMEN were developed: one for networks with temporal redundancy and another for networks with spatial redundancy. Comparative tests were conducted with bio-inspired approaches and local processing strategies in scenarios with and without packet loss. The results indicated that TDMEN can increase network lifetime by up to 75% compared to nonbalanced approaches and by up to 44% compared to bio-inspired approaches. The solution proved effective in different scenarios, both in networks with sensing overlap and in networks without this characteristic, providing superior energy balancing and enhancing overall network efficiency.
