Abstract
In view of Smart-Grid architecture, wireless Last-Mile Network (LMN) devices as smart meters and intelligent home control machines are normally installed in harsh and lossy communication environment. In order to improve communication reliability of LMN, we proposed Wireless Topology Aware Content Centric Networking (TOP-CCN) protocol. TOP-CCN reduces channel access overhead of traditional Content Centric Networking and supports efficient multicast message transmission by using Multiple Point Relay (MPR), and Publisher MPR (PMPR). In addition, TOP-CCN LMN provides simple multi-hop forwarding scheme that can reduce the traditional routing control message overhead in multi-hop wireless LMN environment. The simulation result shows TOP-CCN can improve the service provisioning time and reliability compared to traditional IP based network model in LMN.
Highlights
Power grid management strategy, such as Smart Grid (SG), is rapidly evolving with ICT paradigm.In the SG, reliable smart metering data transmission has to be guaranteed to calculate control power usage, grid load, price, power generation control, etc
Based on a simulation study using ns-3 [5], we show the improved performances of our proposal in terms of communication reliability, network overhead, content downloading time compared to related work
The PMPR selecting algorithm is started by changing the 1-hop and 2-hop table information, and deals with three cases as shown in Algorithm 1: Content Publisher Multiple Point Relay (MPR) selection for content caching
Summary
Power grid management strategy, such as Smart Grid (SG), is rapidly evolving with ICT paradigm. Sci. 2019, 9, 3978 recognition for its abilities to provide efficient end-to-end data dissemination without traditional IP address management overhead From these advantages, CCN is already being exploited in many kinds of wireless applications and services and bound to be utilized in future networking such as Internet-of-things (IoT) [5]. A device who want to receive a specific data transmits an Interest packet with unique, persistent, location-independent name This interest packet is flooded to all network to make backward path to content requester for a certain time. Different from our previous work, we proposed Smart Grid content naming, system model, and content delivery architecture in this paper This proposed architecture focused on network heterogeneity as IP and CCN mixed environment to guarantee interoperability between. Based on a simulation study using ns-3 [5], we show the improved performances of our proposal in terms of communication reliability, network overhead, content downloading time compared to related work
