Wireless sensor networks have become incredibly popular due to the Internet of Things' (IoT) rapid development. IoT routing is the basis for the efficient operation of the perception-layer network. As a popular type of machine learning, reinforcement learning techniques have gained significant attention due to their successful application in the field of network communication. In the traditional Routing Protocol for lowpower and Lossy Networks (RPL) protocol, to solve the fairness of control message transmission between IoT terminals, a fair broadcast suppression mechanism, or Drizzle algorithm, is usually used, but the Drizzle algorithm cannot allocate priority. Moreover, the Drizzle algorithm keeps changing its redundant constant k value but never converges to the optimal value of k. To address this problem, this paper uses a combination based on reinforcement learning (RL) and trickle timer. This paper proposes an RL Intelligent Adaptive Trickle-Timer Algorithm (RLATT) for routing optimization of the IoT awareness layer. RLATT has triple-optimized the trickle timer algorithm. To verify the algorithm's effectiveness, the simulation is carried out on Contiki operating system and compared with the standard trickling timer and Drizzle algorithm. Experiments show that the proposed algorithm performs better in terms of packet delivery ratio (PDR), power consumption, network convergence time, and total control cost ratio.
Within this paper the overlap of issues for lesbians who are also survivors, or survivors who are also lesbians, will be explored in relation t o the impact of mainstream conceptions of meaning around these two aspects of identity. The focus will be on the implications for practioners, who themselves share these aspects of identity with those who use social work services. The importance of engaging in reflexive practice will be highlighted if we are t o work with the tensionskontradications that may arise when personal and professional worlds overlap.ocial work practice is changing as people try to accommodate S shifts in organisational cultures and approaches to management which reflect wider politicalhdeological concerns linked to the rise of the New Right in British politics. The imposition of market forces (Clarke 1996) and hard human resource strategies (Legge 1996), from the private into the public sector, has fundamentally challenged established approaches to social work intervention. Within this context the focus is often on outcomes, in isolation from the processes through which they were generated, for social work practioners and managers (Everitt and Hardiker 1996). This instrumental approach is at variance with the hard won, but fragile recognition that who we are affects how we respond when occupying the social work role. Reflexive approaches to practice enshrine ackowledgement that the shape of our intra psychic worlds, inter personal relationships and the wider structural conditions within which they occur affect the naturehange of responses that are made at the individual and organisational level (Hugman 1992). To make real the intention to engage in anti oppressive practice requires an understanding of the importance of reflexivity, which includes a focus on wider issues than Practice Volume 10 Number 1
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
