Hotspot issue mostly causes of network breakdown and decrease of data packet delivery. Therefore, it is required to design a new technique for data packet forwarding that can resolve these issues in the network. In this study, E2-MBWA has introduced, that cope with the layer-by-layer mechanism for data packet forwarding. The proposed algorithm works with the help of the Data Packet Forwarding Algorithm (DFPA) and Watchman Layer Update Mechanism (WLUM). Furthermore, it also rescues the data storage issues, for this, used secondary nods as substitutes. Moreover, proposed technique is compared with some latest baseline�s approaches, for example, Efficient Traffic Load Reduction Algorithm (ETLRA). The analytical energy model is also described for the best health of the network to measure the accuracy level of the Hotspot issue. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature. %K Digital storage; Energy efficiency, Accuracy level; Data packet delivery; Energy efficient; Layer by layer; Optimal scheme; Packet delivery ratio; Update mechanisms; Wireless sensor and actor networks, Wireless sensor networks %P 69-94 %A U.
