9ire(ess networks are susceptib(e to numerous security threats due to the open nature of

the wire(ess medium. #nyone with a transceiver can eavesdrop on ongoing transmissions" in'ect

spurious messages" or b(ock the transmission of (egitimate ones. he open nature of the wire(ess

medium (eaves it vu(nerab(e to intentiona( interference attacks" typica((y referred to as 'amming.

:amming can interrupt wire(ess transmission and occur by mistake in form of interference" noise

or as co((ision at the receiver or in the circumstance of an attack. his intentiona( interference

with wire(ess transmissions can be used as a (aunch pad for mounting Denia(7of7Service attacks

on wire(ess networks. ypica((y" 'amming has been addressed under an e8terna( threat mode(.

However" adversaries with interna( know(edge of protoco( specifications and network secrets can

(aunch (ow7effort 'amming attacks that are difficu(t to detect and counter. &n se(ective 'amming

attacks" an active 'ammerturns on and off the 'amming signa(s periodica((y or random(y" so the

energy consumption wi(( be (ess and the identification of such a node wi(( be harder. &n the

se(ective 'amming attacks" the adversary is active on(y for a short period of time" se(ective(y

targeting messages of high importance. hose se(ective 'amming attacks can be (aunched by

performing rea(7time packet c(assification at the physica( (ayer. &n this paper" mu(tip(e7path

source routing protoco(s is proposed to a((ow a data source node to distribute the tota( traffic

among avai(ab(e paths. :amming7aware source routing is proposed" in which the source node

performs traffic a((ocation based on empirica( 'amming statistics at individua( nodes and f(ow

optimi;ation prob(em using portfo(io se(ection theory. Here" in mu(ti7source networks" the

centra(i;ed optimi;ation prob(em can be so(ved using a distributed a(gorithm based on
