SEAODV: Secure efficient AODV routing protocol for MANETs networks
, Article ACM International Conference Proceeding Series, 24 November 2009 through 26 November 2009, Seoul ; Volume 403 , 2009 , Pages 940-944 ; 9781605587103 (ISBN) ; Movaghar, A ; Safi, S. M ; Sharif University of Technology
Abstract
Secure routing is one of the most important topics in the wireless MANETs networks. MANETs networks don't have a central infrastructure for the management of routing in the networks. Each node independently routes and sends packets, so many attacks such as forging, modifying, and denial of service (DoS), Occur in these networks. In this paper, we present the new protocol, SEAODV; Secure Efficient Ad-hoc on Demand Routing Protocol for MANETs networks. SEAODV is based on the AODV algorithm and in comparison with existing secure AODV protocols such as SAODV, ARAN and SEAR have improved security and performances. SEAODV uses HEAP authentication Scheme with symmetric cryptography and one-way hash...
Pd(OAc)2 without added ligand as an active catalyst for Mizoroki-Heck reaction in aqueous media

Abstract
Conditions for an efficient ligand-free Heck C-C coupling reaction of aryl iodides and bromides with terminal olefins under aerobic conditions have been developed. Critical to the success of this new protocol is the use of palladium acetate as an extremely active catalyst for the Heck reaction in water and aqueous media. Both the base and the solvent were found to have a fundamental influence on the efficiency of the reaction, with K2CO3 and a mixture of (2:1) H2O/DMSO being the optimal base and solvent, respectively
