As depicted in Fig. 1, a source node aims to send confidential messages to the destination in the presence of M eavesdroppers, with the help of N relays.
In [11], Lai and El Gamal show that a relay node can facilitate the transmission of confidential messages from the source to the destination in the presence of a wiretapper, often referred to as an eavesdropper in the wireless setting.
Here, a computational geometry data structure was proposed to solve the problem of an optimal path generation between a source and a destination, in the presence of simple disjoint polygonal obstacles.
In DF-OWRN, during the first phase of the two-phase communication process, the synchronization between the source and the relays or between the source and the destination (in the presence of direct link) is achieved by estimating and compensating for a single TO and CFO between the source and each relay or between the source and the destination (in the presence of direct link).
Furthermore, the authors in [17] characterize the security-reliability trade-off performance of conventional direct transmission from source to destination in the presence of an eavesdropper, where the security and reliability are evaluated by the intercept probability at the eavesdropper and the outage probability at the destination, respectively.
The routing protocol is chosen here is AODV, which is implemented to route the data packets using cooperative nodes of the network environment, while for routing data packets to the destination in the presence of selfish nodes is carried out through modified version of AODV so that the selfish mobile nodes are isolated without affecting the standard network activities.
Design of robust network topology is an essential issue in large-scale multi-hop wireless networks since data packets are forwarded through intermediate nodes between source and destination, especially in the presence of non-cooperative nodes.
This paper proposes a bargaining-based jammer power allocation scheme for multi-source multi-destination wireless network in the presence of a friendly jammer and a malicious node which eavesdrops erratically.
This household sub-sample was also interviewed about travel histories in the last six months, duration and destination and the presence of fever in the last 14 days and on the day of survey.
Robust joint designs of linear relay precoders and destination equalizers for MIMO relay systems in the presence of noisy or outdated CSI (i.e., imperfect CSI) can be found in [13 18].
