Energyefficient forwarding strategies for geographic routing in lossy wireless sensor networks
- ACM 2nd Conference on Embedded Networked Sensor Systems (SenSys
, 2004
"... Recent experimental studies have shown that wireless links in real sensor networks can be extremely unreliable, deviating to a large extent from the idealized perfect-receptionwithin-range models used in common network simulation tools. Previously proposed geographic routing protocols commonly emplo ..."

-off, whereby energy efficient geographic forwarding must strike a balance between shorter, high-quality links, and longer lossy links. The study is done for scenarios with and without automatic repeat request (ARQ). Based on an analytical link loss model, we study the distance-hop trade-off via mathematical
Minimum-energy packet forwarding over lossy networks under deadline and reliability constraints
"... Abstract—This paper studies minimum-energy packet for-warding over multi-hop lossy networks under deadline and reliability constraints. We assume a routing topology in the form of a directed graph with packet loss processes on links described by finite-state Markov chains, and formulate the for-ward ..."

Energy-Efficient and Reliable Routing Protocol for Wireless Sensor Networks
"... In WSNs routing of data consumes a lot of energy due to excessive flooding of packets. In the proposed EERP scheme routing is done on the basis of intensity of received signals. Unlike REEP, information packet is forwarded by only one source sensor node. The information packets are forwarded by the ..."

Theoretical analysis and simulation results show that the proposed routing protocol is more energy efficient as compared to other existing protocols
Real-Time power-aware routing in sensor networks
- In Proceeding of the IEEE International Workshop on Quality of Service (IWQoS
, 2006
"... Abstract — Many wireless sensor network applications must resolve the inherent conflict between energy efficient communication and the need to achieve desired quality of service such as end-to-end communication delay. To address this challenge, we propose the Real-time Power-Aware Routing (RPAR) pro ..."

RPAR features a power-aware forwarding policy and an efficient neighborhood manager that are optimized for resource-constrained wireless sensors. Moreover
An Adaptive Energy Efficient Reliable Routing Protocol for Wireless Sensor Networks
"... Abstract A reliable routing protocol for wireless sensor networks (WSN) should be capable of adjusting to constantly varying network conditions while conserving maximum power. Existing Routing protocols provide reliability at the cost of high energy consumption. In this paper, we propose to develo ..."

Cooperative Broadcast for Maximum Network Lifetime
"... Abstract — We consider cooperative data broadcast in a wireless network with the objective to maximize the network lifetime. To increase the energy-efficiency, we allow the nodes that are out of the transmission range of a transmitter to collect the energy of unreliably received overheard signals. A ..."

. As a message is forwarded through the network, nodes will have multiple opportunities to reliably receive the message by collecting energy during each retransmission. We refer to this strategy as cooperative (accumulative) broadcast. We present the Maximum Lifetime Accumulative Broadcast (MLAB
Cooperative Multicast for Maximum Network Lifetime
"... Abstract — We consider cooperative data multicast in a wireless network with the objective to maximize the network lifetime. We present the Maximum Lifetime Accumulative Broadcast (MLAB) algorithm that specifies the nodes ’ order of transmission and transmit power levels. We prove that the solution ..."

Energy Efficient Fast Forwarding in Event Driven Wireless Sensor Network (EWSN) using Route Discovery
"... Abstract: In wireless Sensor Network Efficient event detecting protocol (EEDP) is used for event monitoring. In the event occuring area each node broadcasts its primary detection result to make a final decision. The final decision-made by a node will choose the next hop using the underlying routing ..."

- In WASA’07
, 2007
"... In this paper, we study the geographic collaborative for-warding (GCF) scheme, a variant of opportunistic routing, which exploits the broadcast nature and spatial diversity of the wireless medium to improve the packet delivery ef-ficiency. Our goal is to fully understand the principles, the gains, a ..."

We first identify the upper bound of the expected packet ad-vancement (EPA) that GCF can achieve and prove the con-cavity of the maximum
