“…In query-driven model, BS queries SNs' data actively when a SN receives querying request, the SN will send back data as soon as possible. The event-driven packets and query-driven packets have higher priorities to be delivered than the clock-driven data packets [36]. In most hierarchical protocols, CHs allocate TDMA slots to its non-CHs.…”

Abstract-Minimizing energy consumption to maximize network lifetime is one of the crucial concerns in designing wireless sensor network routing protocols. Cluster-based protocols have shown promising energy-efficiency performance, where sensor nodes take turns to act as cluster heads (CHs), which carry out higher-level data routing and relaying. In such case the energy consumption is more evenly distributed for all the nodes. However, most cluster-based protocols improve energy-efficiency at the cost of transmission delay. In this paper, we propose an improved delay-aware and energy-efficient clustered protocol called Hamilton Energy-Efficient Routing Protocol (HEER). HEER forms clusters in the network initialization phase and links members in each cluster on a Hamilton Path, constructed using a greedy algorithm, for data transmission purpose. No cluster reformation is required and the members on the path will take turns to become cluster head. The design allows HEER to save on network administration energy and also balance the load comparing to traditional cluster-based protocols. The algorithms designed in HEER also means that it does not suffer long delay and does not require each node to have global location information comparing with classic chain-based protocols such as PEGASIS and its variations. We implemented the HEER protocol in MATLAB simulation and compared it with several cluster-based and chain-based protocols. We found that HEER is able to achieve an improved network lifetime over the current protocols while maintaining the average data transmission delay. In the simulation, HEER achieved 66.5% and 40.6% more rounds than LEACH and LEACH-EE, which are cluster-based protocols. When compared with chain-based protocols (PEGASIS and Intra-grid-PEGSIS), HEER managed 21.2 times and 16.7 times more rounds than PEGASIS and Intra-grid-PEGASIS respectively. In addition, HEER can eliminated 90% of transmission delay comparing to LEACH and LEACH-EE and 99% comparing with PEGASIS and Intra-grid-PEGASIS. Wireless communication is one of the major power consuming activities on SNs and its usage is controlled mainly by the routing protocol in action. An appropriate protocol design is therefore crucial for minimizing the energy consumption. There are three main types of routing protocols in WSNs, namely flat, hierarchical and location based protocols. KeywordsIn Flat routing protocol, all nodes communicate in a peer-to-peer manner without any hierarchy in the structure. The advantage is having a simple, expandable and low maintenance structure. However, it lacks local and central management of communication resource and usually suffers from long and varied delay.Location-based routing protocols, on the other hand, take in consideration of the location of SNs. Relative coordinates of neighbouring nodes can be extracted from the RF communication between them or, in some cases, by incorporating on-board GPS [3]. However, location tracking devices are huge energy consumers and their performance drops in harsh environme...

“…In fact, the work in [5] proposes an effective way to adapt any camera network to reflect the application monitoring requirements, but it may be inefficient for critical surveillance applications. When a critical event occurs, like an explosion during a popular meeting, more relevant packets must be quickly identified and prioritized by the network, as in [12,21]. Exploiting the concepts of these different approaches, we propose a framework for general-purpose optimizations in camera networks exploiting the relevance of visual source nodes, in a different way of [12,21].…”

“…However, some critical event may trigger high-quality transmissions from the source nodes that can sense the desired event. Thus, the network may have to deal with transmission flows with different relevancies, where prioritization approaches can be employed to support highrelevant transmissions [12].…”

“…The idea is to assure that nodes with higher priority will get more bandwidth, providing weighted fairness in relay nodes. In [12], event-driven transmission flows are prioritized over query-driven and clock-driven transmissions, where prioritization is performed when allocating buffers in sensor nodes. A similar approach is proposed in [21].…”

Camera networks have been considered for a large set of visual monitoring applications. For some of them, cameras may be continuously monitoring scenes or groups of targets, but some events may trigger a critical level of visual monitoring, as in public security, industrial automation, and response to natural disasters. In such way, some critical events as a bomb explosion, a volcanic eruption, forest wildfire, or a car accident must be captured with high relevance, potentially helping when identifying responsibilities and during rescue operations. New relevance levels, which can be reflected in higher quality of transmitted images or video streams or even higher priority during transmission over the network must be quickly assigned to cameras that can view the critical events.In this work we propose a methodology to dynamically assign relevancies to cameras that view the area of critical events, employing scalar sensors and a decentralized decision mechanism. The resulting multimodal camera network can considerably enhance the critical surveillance in different monitoring applications. We propose some optimizations that exploit the monitoring relevance in such scenarios.

“…In some applications of WSN, like the monitoring of an earthquake or forest wildfire, transmitting emergency data packets to the sink node as soon as possible is much more important than saving power. Liu et al, [8] focused on Priority-based Hybrid Protocol WSN model to provide a feasible WSN architecture, which can save the energy of the sensor nodes in normal situation, and transmits emergency data packets in an efficient manner to the sink node. Gajendra et al, [9] has presented the multiple sink mechanism in which sensor nodes are able to deliver data to multiple sink in the network.…”
