A new multi-objective approach for the routing problem in Wireless Multimedia Sensor Networks (WMSNs) is proposed.
•
Classical approximations optimize a single objective or Quality of Service (QoS) parameter.
•
Classical approximations do not take into account the conflicting nature of QoS parameters which leads to sub-optimal solutions.
•
The proposed approach takes into account multiple QoS requirements such as delay and the Expected Transmission Count (ETX).
•
The case studies applying the proposed approach shows clear improvements on the QoS routing solutions.
