| 2 | - Household \wifi{} network penetration keeps increasing to meet the demand of | |
| 3 | - ubiquitous network access. Due to blockage and fading in signal propagation, | |
| 4 | - however, \wifi{} APs can not provide uniform signal coverage within its | |
| 5 | - vicinity. There are cases when a pair of users get better \wifi{} signal from | |
| 6 | - each other's home AP at certain locations within their house, creating | |
| 7 | - reciprocal sharing opportunities where they can improve their network | |
| 8 | - performance by allowing each other to access their own private wifi{} | |
| 9 | - networks. Such sharing relationship is \textit{immediate} between two parties | |
| 10 | - and \textit{stable} over time, making it interesting to explore and practical | |
| 11 | - to establish. | |
| 12 | 2 | |
| 13 | - In this paper, we investigate reciprocal \wifi{} sharing opportunities in real | |
| 14 | - life scenarios through extensive analysis of the 21 million scan results | |
| 15 | - collected from 254 smartphones for 5 months. Reciprocal relationships are | |
| 16 | - revealed despite the spatial sparsity of the dataset. Inspired by the results, | |
| 17 | - we present the design of \wisefi{}, a system that detects and enables | |
| 18 | - reciprocal \wifi{} sharing. | |
| 3 | + Widespread deployment of private home \wifi{} access points (APs) can | |
| 4 | + result in uncoordinated and overlapping wireless networks that compete with | |
| 5 | + each other for limited bandwidth. We expect this suboptimal arrangement to | |
| 6 | + only get worse, particularly in the the dense urban environments that house | |
| 7 | + an increasing fraction of the world's population. Broadband penetration and | |
| 8 | + the demand for high-speed \wifi{} throughout the home will lead to more | |
| 9 | + private APs, which will generate more interference for neighboring | |
| 10 | + networks, resulting in even more private APs and additional interference, | |
| 11 | + and so on. | |
| 12 | + | |
| 13 | + In this paper we investigate whether we can prevent this vicious cycle by | |
| 14 | + using \textit{reciprocal \wifi{} sharing} to make better use of existing | |
| 15 | + private home APs. We define reciprocal \wifi{} sharing as cases where two | |
| 16 | + users both improve their network performance by connecting to each other's | |
| 17 | + overlapping private \wifi{} networks. Compared to previous approaches that | |
| 18 | + attempted to use private APs to create large-scale open-access \wifi{} | |
| 19 | + networks, reciprocal \wifi{} sharing relationships more closely mirror | |
| 20 | + existing human relationships and can be maintained without elaborate | |
| 21 | + reputation mechanisms. | |
| 22 | + | |
| 23 | + To evaluate the effectiveness of reciprocal \wifi{} sharing, we analyze | |
| 24 | + 21~M \wifi{} scans collected from 254~smartphones over 5~months. Our | |
| 25 | + results show that even in a sparsely-populated suburban area, reciprocal | |
| 26 | + \wifi{} sharing is needed. And surprisingly, several reciprocal \wifi{} | |
| 27 | + sharing opportunities exist even among our extremely-small sample of users. | |
| 28 | + Motivated by these results, we present the design of \wisefi{}, a system | |
| 29 | + enabling reciprocal \wifi{} sharing. | |
