Abstract-Network devices always demand full time Internet connectivity for remote access, VoIP & Instant Messaging (IM) clients and other Internet based applications. Their built-in low power management features are usually disabled by users due to their incapability of maintaining network connectivity. The concept of Network Connectivity Proxy (NCP) has recently been proposed as an effective mechanism for reducing energy waste by impersonating presence of sleeping devices. However, proposed strategies in literature for proxying applications are either impractical for today's proprietary applications or limited to only open-source applications. This paper addresses challenges in proxying presence of sleeping devices in order to reduce their network energy waste. To overcome the limitations of NCP concept, this paper proposes an intelligent collaborative proxying scheme which is practically realizable. The proposed system enables network devices to sleep when idle without losing network presence. It can proxy basic networking protocols as well as ensures to run applications on only and only single user device (smartphone, tablet, laptop or office PC) that is actively used at that specific moment. Additionally, the proposed system provides features such as auto-discovery, zero-configuration and seamless communication between devices without requiring any network settings from user.

The NCP design on host's NIC, application specific wake-up, preserving TCP connections and strategies to increase the host's sleep period are addressed in [5].

“…A recent study by Lawrence Berkeley National Laboratory (LBNL) has revealed that about 60% of the office computers are left powered-up 24/7 with existing power management features disabled only to maintain the network connectivity for remote access, Voice-over-IP (VOIP ) clients, Instant Messaging (IM ) and other Internet-based applications [5]. Normally, the Internet-based applications require preserving network connectivity for getting incoming remote service requests or receiving/responding to periodic heart-beat messages.…”

Design and Implementation of Cooperative Network Connectivity Proxy Using Universal Plug and Play

The Future Internet

Abstract.Reducing the network energy waste is one of the key challenges of the Future Internet. Many Internet-based applications require preserving network connectivity for getting incoming remote service requests or confirming their availability and presence to remote peers by sending periodic keep-alive or heart-beating messages. Billions of dollars of electricity is wasted every year to keep idle or unused network hosts fully powered-up only to maintain the network connectivity. This paper describes a new approach to design and implement the cooperative Network Connectivity Proxy (NCP ) for reducing energy waste in the ever-growing future Internet. The NCP is implemented using Universal Plug and Play (UPnP ), that uses a set of protocols to allow seamless discovery and interaction between the network hosts and the NCP. The NCP allows all registered network hosts to transition into the low power sleep modes and maintains the network connectivity on their behalf. It handles basic network presence and management protocols like ICMP, DHCP, ARP etc on behalf of the sleeping network hosts and wakes them up only when their resources are required. Depending on the network hosts time usage model, the NCP can provide about 60 to 70% network energy savings.

“…Impersonating network presence means that the NCP should carry on various networking tasks on behalf of other devices, so that they appear as fully functional and operational to other hosts [3], [7], and it should wake them up when their involvement is unavoidable. Hence, the NCP enables idle devices to enter standby, without losing their network connectivity, and that reduces the energy wasted by idle states.…”

Network Connectivity Proxy: Architecture, Implementation, and Performance Analysis

IEEE Systems Journal

Several studies in the last decade have pointed out that many devices, such as computers, are often left powered on even when idle, just to make them available and reachable on the network, leading to large energy waste. The concept of network connectivity proxy (NCP) has been proposed as an effective means to improve energy efficiency. It impersonates the presence of networked devices that are temporally unavailable, by carrying out background networking routines on their behalf. Hence, idle devices could be put into low-power states and save energy. Several architectural alternatives and the applicability of this concept to different protocols and applications have been investigated. However, there is no clear understanding of the limitations and issues of this approach in current networking scenarios. This paper extends the knowledge about the NCP by defining an extended set of tasks that the NCP can carry out, by introducing a suitable communication interface to control NCP operation, and by designing, implementing, and evaluating a functional prototype
