Handoff processes, the events where mobile nodes select the best access point vailable to transfer data, have been well studied in cellular and WiFi networks. However, wireless sensor networks (WSN) pose a new set of challenges due to their simple low-power radio transceivers and constrained resources. This paper proposes smart-HOP, a handoff mechanism tailored for mobile WSN applications. This work provides two important contributions. First, it demonstrates the intrinsic relationship between

The evaluation shows that handoffs perform the best when operating in the transitional region, as opposed to operating in the more reliable connected region. Second, the results reveal that a proper fine tuning of the parameters,in the transitional region, can reduce handoff delays by two orders ofmagnitude, from seconds to tens of milliseconds. smart-HOP: a reliable handoff mechanism for mobile wireless sensor networks Abstract.
