This article examines the evolution of routing protocols for intermittently connected ad hoc networks and discusses the trend toward social-based routing protocols. A survey of current routing solutions is presented, where routing protocols for opportunistic networks are classified based on the network graph employed. The need to capture performance(More)
Wireless ad hoc networks are seldom characterized by one single performance metric, yet the current literature lacks a flexible framework to assist in characterizing the design tradeoffs in such networks. The aim of this paper is not to propose another routing strategy. Instead, we address this problem by proposing a new modeling framework for routing in ad(More)
On-path caching has been proved to be effective in shortening the content retrieval time and educing the traffic workload imposed on the underlying network. In this paper, we study the effectiveness of on-path caching for the content distribution in the wireless network environment with GPSR as the underlying routing protocol. We extend the general cache(More)
We explore the risks to security and privacy in IoT networks by setting up an inexpensive home automation network and performing a set of experiments intended to study attacks and defenses. We focus on privacy preservation in home automation networks but our insights can extend to other IoT applications. Privacy preservation is fundamental to achieving the(More)
In this paper we address the problem of finding the optimal performance region of a wireless ad hoc network when multiple performance metrics are considered. Our contribution is to propose a novel cross-layer framework for deriving the Pareto optimal performance bounds for the network. These Pareto bounds provide key information for understanding the(More)
As wireless nodes become more powerful, a large volume of diverse content, such as images or videos, become available in a mobile ad hoc network (MANET). It follows that a MANET can largely benefit from the support for "range queries", i.e., a query for content whose attributes are within a requested range. Supporting range queries over MANET is challenging(More)
The tactical edge is filled with rich content, providing real-time intelligence and situation awareness to the warfighter. The current network architecture lacks support for lateral sharing of this critical content. Content is currently accessed from known servers and may require reach-back over bandwidth-constrained links. In this work we present SCALE, a(More)
The authors present SCALE, a content-centric design for MANETs. When possible, SCALE favors routing based on content names to provide local and efficient content retrieval. Geographic hash table (GHT)-like resolution is used as a backup mechanism to ensure a target level of availability as well as scalability. This content retrieval routing decision is made(More)
In this work we examine data delivery in dynamic wireless ad hoc networks that exchange packets opportunistically. Legacy mobile ad hoc network (MANET) protocols send packets along a predetermined path between a source and a destination. Node mobility, however, may create network partitions and a multi-hop link may not be present at the onset. Such node(More)
