Nаziv: | Greedy extension of localized auction based protocols for wireless actuator task assignment | Аutоri: | Mezei, Ivan Malbaša, Vuk Stojmenovic I. |
Dаtum izdаvаnjа: | 1-јан-2013 | Čаsоpis: | Ad-Hoc and Sensor Wireless Networks | Sažetak: | In this paper we assume that all actuators are mobile and an event was reported to one of the actuators, and a response by one actuator is required. The goal of actuator task assignment is to select the best actuator for responding to a reported event so that communication cost for selecting, and response time for performing the task are minimized. Existing solutions, except those proposed in [3] for robot networks, are usually either centralized, neglecting communication cost, assuming complete graph, or based on flooding with individual responses to actuator decision maker (simple auction protocol-SAP), ignoring communication cost and response time bound. This article proposes greedy improvement to previously proposed (in [3]) k-hop simple auction protocol (k-SAP) and k-hop simple auction aggregation protocol (k-SAAP) for task assignment in multi-hop wireless actuator networks. After decision about the best actuator is made by k-SAP or k-SAAP, new 1-SAP greedy auction is initiated by that actuator in order to search for possibly better actuator in 1-hop neighborhood. Such greedy approach proceeds until no better actuator is found. Improvement of new k-SAPG and k-SAAPG over k-SAP and k-SAAP by applying greedy approach is shown by simulation results. © 2012 Old City Publishing, Inc. | URI: | https://open.uns.ac.rs/handle/123456789/15828 | ISSN: | 15519899 |
