“…Packet reliabililty aims to ensure the delivery of every data packet to the sink while event reliability aims to ensure that at least one of many packets from the sensors that detected an event is delivered to the sink. We will provide a brief discussion of event-reliability protocols, which is by no means comprehensive; wider surveys of different reliability protocols for WSNs are available in [6] and [7].…”

Ensuring reliable transport of data in resource constrained Wireless Sensor Networks (WSNs) is one of the primary concerns. The two reliability mechanisms typically used in WSNs are packet reliability and event reliability. Packet reliability requires all packets from all the sensor nodes to reach the sink that can result in wastage of sensors' limited energy resources. The sensing regions of densely deployed sensor nodes often overlap with one another and data from nodes that are in close proximity tend to exhibit high level of spatial locality. This introduces the concept of event reliability where a reliable transfer of event data from each sensing region in a sensor network is sufficient. This paper proposes the Event Reliability Protocol (ERP) that enables reliable transfer of packets containing information about an event to the sink while minimizing similar redundant packets from nodes in the vicinity of one another. ERP builds on the spatial locality condition and employs an implicit acknowledgement (iACK) mechanism with region-based selective retransmissions. The performance of ERP is evaluated and compared against a commonly used iACK scheme to show that ERP significantly improves event information delivery and network scalability, thus maintaining good coverage of events in the sensor network.

There are many wireless sensor network(WSN) applications which require reliable data transfer between the nodes. Several techniques including link level retransmission, error correction methods and hybrid Automatic Repeat reQuest(ARQ) were introduced into the wireless sensor networks for ensuring reliability. In this paper, we use Automatic reSend reQuest(ASQ) technique with regular acknowledgement to design reliable end-to-end communication protocol, called Adaptive Reliable Transport(ARTP) protocol, for WSNs. Besides ensuring reliability, objective of ARTP protocol is to ensure message stream FIFO at the receiver side instead of the byte stream FIFO used in TCP/IP protocol suite. To realize this objective, a new protocol stack has been used in the ARTP protocol. The ARTP protocol saves energy without affecting the throughput by sending three different types of acknowledgements, viz. ACK, NACK and FNACK with semantics different from that existing in the literature currently and adapting to the network conditions. Additionally, the protocol controls flow based on the receiver's feedback and congestion by holding ACK messages. To the best of our knowledge, there has been little or no attempt to build a receiver controlled regularly acknowledged reliable communication protocol. We have carried out extensive simulation studies of our protocol using Castalia simulator, and the study shows that our protocol performs better than related protocols in wireless/wireline networks, in terms of throughput and energy efficiency.

“…Sensors span a large geographical area, and they produce and transmit their measurement packets to a centralized repository (e.g., sink). Due to WSN nature, an end-to-end transport connection is not recommended for largescale sensor networks because of the lack of unique Internetlike addressing for each node, and because it results in large in-network packets and high end-to-end delay [17]. In such networks, sensors typically send their available readings to the nearest in-range nodes [18] so that the amount of traffic is kept low and congestion is avoided.…”

There is an emerging class of applications in which there is a need to reliably transport data from a large number of low rate devices (e.g., hundreds of thousands) to a central server. Atop the list of such applications is smart grid infrastructure. Other applications include meteorological applications, such as monitoring of weather, pollution, and allergy conditions. These applications are characterized by the existence of a large number of small Internet Protocol (IP) devices sending small packets at a low rate to the same server. Even though individual data rates are low, aggregation of these rates produce a significant amount of traffic that can disrupt the communication function of other applications. Because individual devices produce data at a low rate, the transmission control protocol's (TCP) congestion control mechanism is rendered ineffective, thereby causing (i) excessive retransmission of packets; and (ii) degrading the throughput of other competing applications.To address the above problems, we introduce the concept of aggregation at the communication transport level. A TCP aggregator node is added between the data sources and the central server. It splits the TCP connections between the sources (e.g., smart meters) and the data collection server. The aggregator collects data from the individual sources and reliably forwards the data to the collection server. The new strategy provides better response to traffic conditions and, most importantly, makes congestion control and flow control useful. Through extensive NS-2 simulations, we show the effectiveness of the TCP aggregator approach to mitigating the problems in terms of the throughput and packet drop rate performance metrics.
