Wireless Pers Commun https://doi.org/10.1007/s11277-018-5867-2 RA-OABC: An Optimal Framework for Resource Assignment in WCDMA Networks Using Oppositional Artiﬁcial Bee Colony Algorithm with Repair Strategies 1 1 2 • • Saﬁkul Alam S Sourabh Chandra Swapan Bhattacharya Springer Science+Business Media, LLC, part of Springer Nature 2018 Abstract In this paper, we propose a new optimal framework with repair strategy to resolve major issues in the assignment of resources to mobile terminals (plainly to users) in WCDMA networks. The main goal of this proposed approach is to tackle the issues in the assignment of resources such as (1) load factor, (2) total capacity, (3) power, (4) chan- nelization codes and (5) user’s not including any of the service. Our proposed RA-OABC approach adopts the repair strategy for the replacement of resource which violates the weight factor condition (i.e. U B 1). The resource replacement is practiced just by removing the unfeasible resource and substituting it with new feasible resource (repaired versions). The oppositional artiﬁcial bee colony (OABC) algorithm acts well on the groups (assignment of users to the base stations) in a very efﬁcient manner. Moreover, our pro- posed approach also exhibits a superior performance than that of the conventional tech- nique
