“…K is estimated to be big enough to contain the effective sending of some messages, even if some collisions occur. The use of this strategy could have an undesired effect, because the collisions cannot be detected without the use of ACK [19], in these conditions, if in a K time interval some collisions occurs, the node could not be able to differentiate it from the fact that perhaps no message has arrived, and could go to sleep, even though the message that collided has not arrived effectively yet. Although that message is stored at its sender, and could be selected for a further re-send, this phenomenon introduces additional delays, which can potentially increase latency on collided messages.…”

In WSNs, several strategies are being developed to guarantee the delivery of information messages. Despite the fact that these efforts increase the delivery rate, they also imply an additional network overhead that could drain the node´s batteries power. As a result, if a node runs out of battery power before its time it will not be able to deliver data anymore, thus affecting the whole system's operation. This research compares two confirmation delivery strategies based on explicit and implicit acknowledgment, which could take advantage of wireless communication features to deliver sensed data with efficiency, and also manage the node energy resources in such a way that the continuous operation of the WSNs could be extended. A WSN simulation model on Visual Sense/Ptolemy II modeling framework was built to compare these two acknowledgment strategies. As a result of this evaluation we can see that the implicit acknowledgment strategy reaches a slightly better reliability with a lower cost

“…Since the energy consumption strongly depends on the range between sensors [22], SPMS [23] [24] could reduce the energy consumption using multi-hop path based on the shortest path. SPMS lessens the consumed power and shortens disseminated time compared with SPIN, and it is fault tolerant.…”

A Robust Energy Saving Data Dissemination Protocol for IoT-WSNs

In Wireless Sensor Networks (WSNs) for Internet of Things (IoT) environment, fault tolerance is a most fundamental issue due to strict energy constraint of sensor node. In this paper, a robust energy saving data dissemination protocol for IoT-WSNs is proposed. Minimized energy consumption and dissemination delay time based on signal strength play an important role in our scheme. The representative dissemination protocol SPIN (Sensor Protocols for Information via Negotiation) overcomes overlapped data problem of the classical Flooding scheme. However, SPIN never considers distance between nodes, thus the issue of dissemination energy consumption is becoming more important problem. In order to minimize the energy consumption, the shortest path between sensors should be considered to disseminate the data through the entire IoT-WSNs. SPMS (Shortest Path Mined SPIN) scheme creates routing tables using Bellman Ford method and forwards data through a multi-hop manner to optimize power consumption and delay time. Due to these properties, it is very hard to avoid heavy traffic when routing information is updated. Additionally, a node failure of SPMS would be caused by frequently using some sensors on the shortest path, thus network lifetime might be shortened quickly. In contrast, our scheme is resilient to these failures because it employs energy aware concept. The dissemination delay time of the proposed protocol without a routing table is similar to that of shortest path-based SPMS. In addition, our protocol does not require routing table, which needs a lot of control packets, thus it prevents excessive control message generation. Finally, the proposed scheme outperforms previous schemes in terms of data transmission success ratio, therefore our protocol could be appropriate for IoT-WSNs environment.
