“…This sleeping technique can be adopted by emergency ad hoc network but cannot substitute an energy efficient distributed routing algorithm. An interesting framework is proposed in [15] that enables nodes to harvest energy from an undamaged base station (source) and then act as a relay to carry the information to an area that does not have direct access to the source. The authors propose an optimal communication route for networks during an emergency to minimize end-to-end disconnection and reduce energy consumption while introducing the concept of Radio Frequency (RF)-based energy harvesting.…”

Natural and man-made disasters have been causing destruction and distress to humanity all over the world. In these scenarios, communication infrastructures are the most affected entities making the rescue and emergency response operations extremely challenging. This invokes a need to equip the affected people and the emergency responders with the ability to rapidly set up and use independent means of communication. Therefore, in this work, we present a complete endto-end solution that can connect survivors of a disaster with each other and the authorities using a completely self-sufficient ad hoc network that can be setup rapidly. Accordingly, we develop a Heterogeneous Efficient Low Power Radio (HELPER) that acts as a WiFi (Wireless Fidelity) access point for end-users to connect using website application developed by us. These HELPERs then coordinate with each other to form a LoRa based ad hoc network. To this end, we propose a novel cross-layer optimized distributed energy-efficient routing (SEEK) algorithm that aims to maximize the network lifetime. This aspect is critical especially in energy constrained scenarios after a disaster.To prove the feasibility of the solutions, we prototype the HELPER using WiFi enabled Raspberry Pi and LoRa module that is configured to run using Li-ion batteries. We implement the required cross-layer protocol stack along with the SEEK routing algorithm and develop a website application that an end-user can avail to connect using any device such as smartphones, tablets, laptops etc. We have conducted demonstrations to establish the feasibility of exchanging of text messages over the HELPER network, live map updates, ability to send distress messages (like 9-1-1 calls) to authorities. In the context of authorities, we have shown how they can leverage this technology to remotely monitor the connectivity of the affected area, alert users of imminent dangers and share resource (water, food, first aid) availability information. We have also conducted an extensive numerical evaluation of SEEK algorithm against a greedy geographical routing algorithm using the HELPER testbed. Results showed up to 53% improvement in network lifetime and up to 28% improvement in throughput. Overall, we hope this technology will become instrumental in improving the efficiency and effectiveness of public safety activities.

“…One of the fundamental motivation behind using Device-to-Device (D2D) communication underlaying cellular networks is to enable direct connection between a pair of proximity devices without involvement of Base Station (BS). Although in the current cellular systems, D2D communications along with the development of small cells can cover a large area providing an enhanced Quality-of-Service (QoS), this may require a considerably increased operating expense [1][2][3][4][5].…”

“…D2D communication provides new mobile service opportunities and potential capability to reduce the traffic load in cellular networks [18]. In addition, D2D communications can be applied to mission-critical applications such as providing public safety and disaster monitoring and relief services due to the low-cost deployment and low-complexity configuration of D2D devices [19]- [22]. Furthermore, D2D communications can improve the spectral utilization via enabling direct communication between the neighbouring mobile devices without the involvement of BS, which is well suited for high data rate, delay constrained and quality of service (QoS)specific communication [23].…”

A device-to-device (D2D) ultra reliable low latency communications (URLLC) network is investigated in this paper. Specifically, a D2D transmitter opportunistically accesses the radio resource provided by a cellular network and directly transmits short packets to its destination. A novel performance metric is adopted for finite block-length code. We quantify the maximum achievable rate for the D2D network, subject to a probabilistic interference power constraint based on imperfect channel state information (CSI). First, we perform a convexity analysis which reveals that the finite block-length rate for the D2D pair in short-packet transmission is not always concave. To address this issue, we propose two effective resource allocation schemes using the successive convex approximation (SCA)-based iterative algorithm. To gain more insights, we exploit the monotonicity of the average finite block-length rate. By capitalizing on this property, an optimal power control policy is proposed, followed by closed-form expressions and approximations for the optimal average power and the maximum achievable average rate in the finite block-length regime. Numerical results are provided to confirm the effectiveness of the proposed resource allocation schemes and validate the accuracy of the derived theoretical results.Index Terms-Finite block-length codes, URLLC, average achievable rate, performance analysis, optimal power allocation.
