    We study the real-time data aggregation in contention-based wireless sensor networks that use CSMA/CA MAC layer protocols as defined in IEEE 802.15.4 or IEEE 802.11 standard. The problem is, for a given data aggregation tree and a delay bound, to maximize the overall transmission success probability of all sensor nodes within the delay bound. In CSMA/CA protocols, the success probability and the e... View full abstract»
